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 par-
allel and clock frequency should be interpreted as
166 MHz. (The precise rates are 2.66606 Gbits/s and
166.62 MHz.)
The devices contain a limiting amplifier with 30 dB
gain, a clock and data recovery PLL with high-speed
serial clock and data outputs, and a 1:16 demulti-
plexer with differential PECL data and clock outputs.
The device provides improved optical receiver perfor-
mance when used in optically amplified systems due
to a direct slice adjust input pin and a 6 ps adjust-
ment capability in the slicing decision time. Both
devices are available in either BiCMOS or in SiGe
BiCMOS technology for lower power operation.
