Functional Overview
This highly integrated module converts a 4.096 Mb/s
fiber-optic NRZ signal to differential PECL data outputs.
A single +5 Volt supply provides bias for the module’s
preamplifier, and Quantizer. The photodiode is biased
internally. All elements are integrated into fiber-coupled
1.3” X 0.635” 20 pin DIL package. The RXM-4 footprint
and pinout are industry common for ease of integration.
The optical signal is coupled through a 62.5
μ
m
multimode optical fiber to a hermetic module which
encases an InGaAs PiN-photodiode and preamplifier.
The PiN-photodiode converts the optical signal to an
electrical current.
The signal is then converted to a voltage and amplified
by a low noise transimpedance amplifier, further gain is
provided by the quantizer. Following the quantizer is an
ECL 10H116-type differential buffer.
