The DS31408DK is an easy-to-use evaluation kit for the DS31408 timing IC. A surface-mounted DS31408 and careful layout provide maximum signal integrity. An onboard low-phase-noise stratum 3 quality oscillator is provided for device compliance evaluation. Additionally, the board can accept an external oscillator input for testing alternate oscillators and oscillator frequencies. All eight DS31408 input clocks are accessible via a combination of SMA and SMB connectors. These input clocks are terminated on board as four differential AC-coupled, and four single-ended DC-coupled inputs to allow easy evaluation of a wide range of input clock signal formats. All 14 DS31408 output clocks are accessible via a combination of SMA and SMB connectors to allow easy evaluation of the device’s CML, LVDS/LVPECL, and CMOS output clock signals. LEDs on the board indicate interrupt, DPLL lock, selected reference fail, and GPIO output status. Additionally, the GPIO, interrupt, and JTAG I/O signals are also accessible via header pins. Finally, an onboard microcontroller and USB interface provide easy configuration and monitoring of the DS31408 via a software application.
