The MAX3882 is a deserializer combined with clock

and data recovery and limiting amplifier ideal for con-

verting 2.488Gbps/2.67Gbps serial data to 4-bit-wide,

622Mbps/667Mbps parallel data for SDH/SONET appli-

cations. The device accepts serial NRZ input data as

low as 10mV

four parallel LVDS data outputs at 622Mbps/667Mbps.

Included is an additional high-speed serial data input

for system loopback diagnostic testing. For data acqui-

sition, the MAX3882 does not require an external refer-

ence clock. However, if needed, the loopback input

can be connected to an external reference clock of

155MHz/167MHz or 622MHz/667MHz to maintain a

valid clock output in the absence of input data transi-

tions. Additionally, a TTL-compatible loss-of-lock output

is provided. The device provides a vertical threshold

adjustment to compensate for optical noise generated

by EDFAs in WDM transmission systems. The MAX3882

operates from a single +3.3V supply and consumes

610mW.

The MAX3882’s jitter performance exceeds all SDH/

SONET specifications. The device is available in a 6mm

19-2718; Rev 0; 1/03
