PX6420 10 Gb/s receiver is a
single channel TIA/LA optical receiver designed for
various 10 Gb/s PMD applications. It consists of a
transimpedance amplifier and an AC-coupled
differential limiting amplifier.
The transimpedance amplifier 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 is AC-coupled
internally to a high-gain, high-bandwidth, limiting
amplifier. The limiting amplifier 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.
