TTRN012G7 Datasheet | Agere Systems

Preliminary Data Sheet August 2000 TTRN012G5 (2.5 Gbits/s) and TTRN012G7 (2.5 Gbits/s and 2.7 Gbits/s) Clock Synthesizer, 16:1 Data Multiplexer Features s s Description The Lucent Technologies Microelectronics Group TTRN012G5 operates at the OC-48/STM-16 data rate of 2.5 Gbits/s. The TTRN012G7 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 TTRN012G5 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 TTRN012G7 at the FEC rate, the 2.5 Gbits/s data rate should be interpreted as 2.7 Gbits/s...
