PX5524 4 x 4 Gb/s TIA/LA Receiver Product Brief
April 2006
Description The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand for 40+ Gb/s WAN bandwidth fuels the growth of short-reach 10 Gb/s infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links. The Zarlink PX5524 4 Gb/s TIA/LA Receiver is a four-channel TIA/LA optical receiver designed for various 4x4 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 3 GHz bandwidth over a wide range of photodiode input capacitance.
