R485-Type Lightwave Receiver with Clock
Recovery for 2.488 Gbits/s Applications
Manufactured in a low-profile, 24-pin package, the R485-Type
Receiver features either an avalanche or PIN photodetector, a
transimpedance amplifier, a limiting amplifier, and a clock and
data recovery IC.

Description
The R485-Type 2.5 Gbits/s lightwave receiver is
designed for use in SONET OC-48 and synchronous
digital hierarchy (SDH) STM-16 telecommunications
applications and high-speed data communications
applications. The receiver converts received optical
signals in the range of 1.2
μ
m to 1.6
μ
m wavelength
into differential data and clock outputs. The receiver
consists of either InGaAs APD or PIN photodetector
(depending on model selected), a transimpedance
amplifier, a limiting amplifier, and a clock and data
recovery IC (CDR). The CDR uses PLL technology to
extract the clock signal from the converted optical
signal. A TTL compatible link status flag signal indi-
cates when there is a loss of optical signal.
The receiver is manufactured in a low-profile, pig-
tailed, 24-pin plastic DIP package. It requires a sin-
gle, +5.0 V power supply. The APD version has the
added benefit of containing the high-voltage supply
internal to the receiver. This internal supply also pro-
vides the necessary temperature compensation for
the APD.
