Description

The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance. The demand and availability of 10 Gb/s+ WAN bandwidth fuels the growth of native 10 Gb/s infrastructures within MAN and enterprise datacenters.

The Primarion® PX6420 10 Gb/s receiver is a single channel TIA/LA optical receiver designed for various 10 Gb/s PMD applications. PX6420 consists of a transimpedance amplifier and an AC-coupled differential limiting amplifier.

The transimpedance amplifier PX6420 achieves a nominal bandwidth of 8 GHz over a wide range of photodiode input capacitance. A photodiode bias current monitor allows for a simple alignment procedure.

The transimpedance amplifier PX6420 is AC-coupled internally to a high-gain, high-bandwidth, limiting amplifier. The limiting amplifier PX6420 provides a differential back-terminated CML output that can be used to drive 10 Gb/s Serdes or other CML compatible circuits.

Full diagnostics are delivered through loss of signal, squelch, and received signal strength indicator circuits.
