Description
The Agere Systems Inc. TRCV0112G device inte-
grates a limiting amplifier combined with a clock
recovery circuit that feeds a data demultiplexer for
use in 12 Gbit/s high-speed communications sys-
tems. Additional features include an auxiliary clock
output and a reference clock input that can be either
16 or 64. The device will operate in two frequency
ranges 9.95328 Gbit/s through 10.70922 Gbit/s or
12 Gbit/s through 12.5 Gbit/s. The higher rate is pin
selectable.
Functional Overview
The TRCV0112G performs the data detection, clock
recovery, and 1:16 demultiplexing operations
required to support 10 Gbits/s
OC-192/STM-64
applications compliant with Telcordia Technologies
and ITU standards. One of two high-speed inputs
can be selected as the data source. A PLL recovers
the clock which is used to retime the data. A 1:16
data demultiplexer performs the serial-to-parallel
conversion and generates 16 parallel outputs at
622 Mbits/s. The parallel output data is aligned to a
622 MHz clock derived from the 10 GHz recovered
clock.
FEC Rate Support
The TRCV0112G will support the rates of
9.95328 GHz through the rate of 10.70922 GHz
(FECN = 1) and higher FEC rates of 12.0 GHz
through 12.5 GHz (FECN = 0). The FECN pin
selects between VCO ranges of 9.95328 GHz
through 10.70922 GHz and 12.0 GHz through
12.5 GHz. All frequency-based specifications are to
be multiplied by (rate/9.95328 GHz) when operating
at higher frequency rates.
The OC-192/STM-64 data rate of 9.95328 Gbits/s is typically
approximated as 10 Gbits/s in this document when referring to
the application rate. Similarly, the low-speed parallel interface
data rate of 622.08 Mbits/s is typically approximated as
622 Mbits/s. The exact frequencies are used only when neces-
sary for clarity.

FEC Rate Support
(continued)
All time-based specifications, with the exception of electrical signal rise and fall times, are to be multiplied by
(9.95328 GHz/rate). At nonstandard FEC rates, the reference clock would need to be applied at
(rate/9.95328 GHz) 155.52 MHz or (rate/9.95328 GHz) 622.08 MHz and the paralled data interface would
operate at (rate/9.95328 GHz) 622.08 MHz.
