1. General Information:

️· Device: Lucent Technologies TRCV012G5 and TRCV012G7
️· Function: Limiting Amplifier, Clock Recovery, 1:16 Data Demultiplexer
️· Data Rates Supported: 2.488 Gbps (OC-48/STM-16) and 155.52 Mbps. The documentation notes that the 155 Mbps data rate might require adjustments based on FEC status.

2. Pin Naming Conventions:

️· Differential Pairs: Differential pins are indicated with a "P" (positive) and "N" (negative) suffix.
️· Single-Ended Pins: If a pin has no suffix, it is a single-ended signal.
️· Active-Low: Pins with an "N" at the end are considered active-low.
️· Resistor Notation:
- I [u] = Internal pull-up resistor.
- I [d] = Internal pull-down resistor.
- I [t] = Internal termination resistance of 50 ohms.

3. Pin Descriptions (2.488 Gbps/OC-48/STM-16):

This section lists several pins related to data output. These are described in detail in the provided tables. The specific pin names and their functions are detailed in the original text. (See details below).

4. Pin Descriptions (155.52 Mbps):

This section lists numerous data output pins (D0P, D0N through D15P, D15N) used for transmitting data at a rate of 155.52 Mbps. The tables are described in detail in the original text.

Important Notes Mentioned:

️· When operating the TRCV012G7 device at the OC-48/STM-16 rate, 155 Mbps should be interpreted as 155.52 Mbps.
️· When operating the TRCV012G7 device at the RS FEC OC-48/STM-16 rate, 155 Mbps should be interpreted as 166.62 Mbps. (And a similar interpretation should be made for 155 MHz).
