General Description
The HMC690 is 10 Gbps transimpedance amplifier
designed for SONET OC-192 / SDH STM-64, 10GbE
and 10Gbps systems employing optical amplifiers. It
supports data rates up to 11.3 Gbps. This amplifier
provides a differential output voltage that is proportional
to an applied current at its input port. This current is
typically provided by a photodiode. Operating from a
single +3.3V supply, the HMC690 features low input
referred noise, and is designed for driving a CDR or
a typical transceiver directly. The RSSI output can be
used for monitoring average input power. This device
also features a DC offset control, which enables
output signal level adjustment for asymmetrical
signals. Additional features include an integrated
300Ω filter resistor for photo-diode supply voltage and
an extended linear range^[2] option.
