12 x 10 Gb/s TIA/LA Optical Receiver
Product Brief
April 2005
Description
The growing use of the Internet has created
increasingly higher demand for multi-Gb/s I/O
performance. The demand for 100+ Gb/s WAN
bandwidth fuels the growth of short-reach 120
Gb/s infrastructures within high-end telco and
datacom routers, switches, servers and other
proprietary chassis-to-chassis links. The Zarlink
PX6429 120 GB/s TIA/LA Receiver is a 12-
channel TIA/LA optical receiver designed for
various 12x10 Gb/s, 10 Gb/s parallel optics and
CWDM PMD applications. It consists of a DC
coupled transimpedance amplifier and an AC
coupled differential limiting amplifier.
The transimpedance amplifier achieves a nominal
8 GHz bandwidth over a wide range of photodiode
input capacitance. Excellent channel-to-channel
isolation ensures data integrity at the receiver
sensitivity limits. A global signal detect circuit
provides the photodiode reverse bias voltage
supply and senses average photocurrent supplied
to the photodiode array.
The transimpedance amplifier is AC-coupled
internally to a high-gain, high-bandwidth
differential limiting amplifier. The limiting amplifier
provides a differential back-terminated CML
output that can be used to drive 10 Gb/s per
channel transceivers or other CML compatible
clock and data recovery circuits. The limiting
amplifier features an adjustable signal detect
circuit that senses optical modulation amplitude
(OMA) to provide a received signal indication for
each channel.
