AMC002

Telco/Fabric Clock Breakout, single-width AMC

A MicroTCA clock and GPS board is an AMC plug-in module that provides precise timing, synchronization, and location/time reference to a MicroTCA system.

It typically includes:

A GPS/GNSS receiver
A precise local oscillator, such as an OCXO
Clock-generation and distribution circuits
Timing inputs and outputs such as 1 PPS, 10 MHz, trigger, or event signals
Interfaces to distribute timing through the MicroTCA backplane
Sometimes support for IEEE 1588 PTP, SyncE, IRIG-B, or White Rabbit

A GPS board receives satellite signals through an external antenna. It then generates an accurate time reference and synchronized clocks for FPGA, RFSoC, ADC, DAC, and processor modules.

Common uses include:

Synchronizing multiple data-acquisition channels
Timestamping measurements and events
Aligning ADC and DAC sampling clocks
Coordinating several MicroTCA chassis
Radar, telecommunications, scientific instruments, and accelerator-control systems

Description:

AMC002 provides a convenient way to monitor and/or inject Telco clocks with a μTCA/ATCA system utilizing either AMC v1 or AMC v2 clock pin-out definitions. Two clocks may be injected while at the same time three clocks may be monitored. The clocks in use for both input and output are selectable by on-board switches. Clock signals are automatically converted between M-LVDS backplane signaling and front panel +3.3V LVCMOS signaling.

An option is provided for monitoring the fabric (i.e. PCIe) clock using HCSL signaling under AMC v2 or CLK3 using M-LVDS signaling under AMC v1. Clocks are conditionally driven to the backplane based on front panel clock transmit enable switches. Indicators on the front panel clearly show the current clocking configuration of the board.
