DS31415DK Datasheet

The DS31415DK is an easy-to-use evaluation kit for the DS31415 timing IC. A surface-mounted DS31415 and careful layout provide maximum signal integrity. An onboard low-phase-noise TCXO is provided for device compliance evaluation. Additionally, the board can accept an external oscillator input for testing alternate oscillators and oscillator frequencies. Both DS31415 input clocks are accessible via SMA connectors. All DS31415 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 on-board microcontroller and USB interface provide easy configuration and monitoring of the DS31415 via a software application.
