Description
The Agere Systems Inc. TTRN0110G device
provides a 16:1 multiplexer, accepts 16 differential
LVDS data inputs and a 155.52 MHz or 622.08 MHz
reference clock, and generates a CML 10 Gbits/s
clock and data output. Both forward directional and
contradirectional clocking schemes are supported for
transferring data across the parallel interface. When
contraclocking is used, the TTRN0110G provides
one of four phases of a 622.08 MHz clock output
back upstream to the data chip. The device also
supports a clockless parallel data transfer mode. The
TTRN0110G can be operated within the standard
OC-192/STM-64 data rate of 9.9532 GHz and the
FEC rate of 10.7092 Gbits/s.
