## Abstract
|
|
|
|
|
|
An FPGA Mezzanine Card (FMC) for clock & data recovery (CDR) from
|
|
|
optical sources. Its major components are a commercial clock/recovery
|
|
|
IC, an optical receiver with FC connector and an SFP+ cage. The boards
|
|
|
also offers two coaxial I/O connectors (LEMO series 00). The FMC is
|
|
|
often referred-to as TTC FMC since it can play the role of Timing
|
|
|
Trigger and Control (TTC) receiver for particle physics applications
|
|
|
(together with the associated FPGA firmware).
