trcv012g5 ETC-unknow, trcv012g5 Datasheet - Page 3

• Manufacturer Part Number: trcv012g5
• Description: Trcv012g5 Gbits/s Trcv012g7 Gbits/s Gbits/s Limiting Amplifier, Clock Recovery, Data Demultiplexer
• Manufacturer: ETC-unknow

Preliminary Data Sheet
August 2000
Description
Additional features include a user-programmable threshold for generating analog loss of signal (LOS) alarms, a
digital LOS transition detector, an optional reference clock input that can maintain synchronization with no data
input signal present, and a loopback data input. To reduce power consumption, the demultiplexer unit, high-speed
serial recovered data and clock output, low-speed clock, and low-speed demultiplexer clock output can be inde-
pendently powered down in applications where they are not required.
The device may be used with the TTRN012G5 or TTRN012G7 transmit synthesizer and multiplexer.
Note: Diagram is representative of device functionality and conceptual signal flow. Internal implementation details may be different than shown.
