The DS3104-SE is in the center of the board, input clock SMB connectors are along the left edge of the board, and output clock connectors are on the right edge. Between the input clock connectors and the DS3104-SE, land patterns are provided for several different types of local oscillators, ranging from inexpensive XOs to higher performance TCXOs. The top edge contains, from left to right, power-supply connectors, DC-DC converters and power-indicator LEDs, reset pushbutton, serial connector, and USB connector. An on-board DS87C520 microcontroller is located near the USB connector. The bottom edge of the board is occupied by a JTAG connector and LED indicators. See Appendix 1 Hardware Components for a complete component list. Complete board schematics follow in Section Figure DS3104DK Board Floorplan 4 of 35 DS3104DK Input and Output Clocks There are seven SMB connectors at the left of the board labeled IC3, IC4, IC7, IC8, and that provide a single-ended clock input to the DS3104-SE. All single-ended clock inputs are connected to the DS3104-SE with a 50Ω characteristic impedance trace and terminated with 50Ω at the device require a jumper in the TERM position to terminate due to dual functionality . Eight additional SMB connectors labeled IC1P, IC1N, IC2P, IC2N, IC5P, IC5N, IC6P, and IC6N provide differential clock inputs to the DS3104-SE. These differential inputs have 50Ω trace impedance, test points, and 50Ω termination at the device i.e., 100Ω differential . On the other side of the PCB are 12 SMB clock output connectors labeled FSYNC, and MFSYNC. All single-ended clock outputs are buffered at the DS3104-SE and connected to the SMB connector via a 50Ω characteristic impedance trace. Cables attached to the single-ended output connectors must have 50Ω termination and characteristic impedance for proper operation. Eight additional SMB connectors labeled OC4P, OC4N, OC5P, OC5N, OC6P, OC6N, OC7P, and OC7N provide connections to the differential outputs from the DS3104-SE. Jumpers, Headers, and Switch Settings Jumpers and JMP16 lower right of board provide the means to pull up or pull down the TEST, SRFAIL, LOCK, SRCSW, and SONSDH pins of the DS3104-SE. Note that some of these jumpers only make sense for other DS310x products where the pin has a different function. Labels specify which position is used to pull each pin to a 1 or a 0 if jumper is not installed, pin is left to float to accommodate a pin’s output function . Jumpers middle right of board provide access to the and IC9 pins of the DS3104-SE. Labels specify the position to install the jumper to pull the pin up signified by “1” or pull it down through a 50Ω resistor signified by The 50Ω resistor is used as a termination resistor when the pin is used as a input clock signal. Jumper JMP6 labeled VDDIOB is used to set the VDDIOB supply voltage for output clock pins The options are labeled for 2.5V or 3.3V. Jumpers JMP62 and JMP63 select the computer interface to be USB or RS-232. Jumper JMP5 upper-left selects whether the board should be powered from the USB connector or from the power-supply jacks J3 or J13/J19 . LEDs upper-left indicate the labeled power supply is operational. LED DS16 upper-right indicates that the microprocessor is operational. LEDs DS5, DS6, and DS10 lower middle indicate the status of the SRFAIL, LOCK, and INTREQ pins, respectively. Switch SW1 is used to select a squaring circuit to accommodate a sinusoidal input on IC3. Header J51 provides access to the JTAG port of the DS3104-SE. Test points are provided for differential inputs and outputs, the watchdog timer pin, SPI port pins, and ground plane connection. Microcontroller The DS87C520 microcontroller has factory-installed firmware in on-chip nonvolatile memory. This firmware translates memory access requests from the RS-232 serial port or USB port into register accesses on the DS3104-SE. When the microcontroller starts up it turns on DS16 to indicate that the controller is working correctly. A pushbutton switch labeled RESET near the RS-232 connector resets the microcontroller as well as the DS3104-SE. Power-Supply Connectors A 5V lab power supply can be connected across the red J13 and black J19 banana jacks. Optionally, the board can be powered from the USB connector by placing jumper JMP5 in the USB position. The 5V input from either of these sources is then regulated to 3.3V, 2.5V, and 1.8V, and distributed to board components. Note that the board cannot be USB powered through some USB hubs. Before trying to power the board through a USB hub, check the voltage at JMP5 to ensure the board is getting 5V from the hub. 5 of 35 DS3104DK

Input and Output Clocks

There are seven SMB connectors at the left of the board labeled IC3, IC4, IC7, IC8, and that provide a single-ended clock input to the DS3104-SE. All single-ended clock inputs are connected to the DS3104-SE with a 50Ω characteristic impedance trace and terminated with 50Ω at the device require a jumper in the TERM position to terminate due to dual functionality . Eight additional SMB connectors labeled IC1P, IC1N, IC2P, IC2N, IC5P, IC5N, IC6P, and IC6N provide differential clock inputs to the DS3104-SE. These differential inputs have 50Ω trace impedance, test points, and 50Ω termination at the device i.e., 100Ω differential .

On the other side of the PCB are 12 SMB clock output connectors labeled FSYNC, and MFSYNC. All single-ended clock outputs are buffered at the DS3104-SE and connected to the SMB connector via a 50Ω characteristic impedance trace. Cables attached to the single-ended output connectors must have 50Ω termination and characteristic impedance for proper operation. Eight additional SMB connectors labeled OC4P, OC4N, OC5P, OC5N, OC6P, OC6N, OC7P, and OC7N provide connections to the differential outputs from the DS3104-SE.

Jumpers, Headers, and Switch Settings

Jumpers and JMP16 lower right of board provide the means to pull up or pull down the TEST, SRFAIL, LOCK, SRCSW, and SONSDH pins of the DS3104-SE. Note that some of these jumpers only make sense for other DS310x products where the pin has a different function. Labels specify which position is used to pull each pin to a 1 or a 0 if jumper is not installed, pin is left to float to accommodate a pin’s output function . Jumpers middle right of board provide access to the and IC9 pins of the DS3104-SE.

Jumper JMP6 labeled VDDIOB is used to set the VDDIOB supply voltage for output clock pins The options are labeled for 2.5V or 3.3V. Jumpers JMP62 and JMP63 select the computer interface to be USB or RS-232. Jumper JMP5 upper-left selects whether the board should be powered from the USB connector or from the power-supply jacks J3 or J13/J19 . LEDs upper-left indicate the labeled power supply is operational. LED DS16 upper-right indicates that the microprocessor is operational. LEDs DS5, DS6, and DS10 lower middle indicate the status of the SRFAIL, LOCK, and INTREQ pins, respectively. Switch SW1 is used to select a squaring circuit to accommodate a sinusoidal input on IC3. Header J51 provides access to the JTAG port of the DS3104-SE. Test points are provided for differential inputs and outputs, the watchdog timer pin, SPI port pins, and ground plane connection.

Microcontroller

The DS87C520 microcontroller has factory-installed firmware in on-chip nonvolatile memory. This firmware translates memory access requests from the RS-232 serial port or USB port into register accesses on the DS3104-SE. When the microcontroller starts up it turns on DS16 to indicate that the controller is working correctly. A pushbutton switch labeled RESET near the RS-232 connector resets the microcontroller as well as the DS3104-SE.

Power-Supply Connectors

A 5V lab power supply can be connected across the red J13 and black J19 banana jacks. Optionally, the board can be powered from the USB connector by placing jumper JMP5 in the USB position. The 5V input from either of these sources is then regulated to 3.3V, 2.5V, and 1.8V, and distributed to board components.

Note that the board cannot be USB powered through some USB hubs. Before trying to power the board through a USB hub, check the voltage at JMP5 to ensure the board is getting 5V from the hub.
