12 X 3 Gbps Optical Receiver With ACJTAG

The growing use of the Internet has created increasingly higher demand for multi-Gbps I/O performance. The demand for 100+ Gbps WAN bandwidth fuels the growth of short-reach 40 Gbps infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links. The Zarlink PX5429A 12x3 Gbps TIA/LA Receiver with ACJTAG is a twelve channel TIA/LA optical receiver designed for various 12x3 Gbps parallel PMD applications. It consists of a DC-coupled Transimpedance Amplifier and an AC-coupled differential Limiting Amplifier The Transimpedance Amplifier achieves a nominal 3 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.
