Description
The Lucent Technologies Microelectronics Group TRCV012G5 operates at the OC-48/STM-16 data rate of 2.5 Gbits/s. The TRCV012G7 device operates at either 2.5 Gbits/s or the RS FEC OC-48/STM-16 data rate of 2.7 Gbits/s. For clarity, this data sheet refers to the TRCV012G5 serial data rate as 2.5 Gbits/s and the parallel data and reference clock frequency as 155 MHz. (The precise rates are 2.48832 Gbits/s and 155.52 MHz.) When using the TRCV012G7 at the FEC rate, the 2.5 Gbits/s data rate should be interpreted as 2.7 Gbits/s and the parallel and clock frequency should be interpreted as 166 MHz. (The precise rates are 2.66606 Gbits/s and 166.62 MHz.)
