The MAX3885 deserializer is ideal for converting
2.488Gbps serial data to 16-bit wide, 155Mbps parallel
data in SDH/SONET applications. Operating from a sin-
gle +3.3V supply, this device accepts PECL serial
clock and data inputs, and delivers low-voltage differ-
ential-signal (LVDS) clock and data outputs for interfac-
ing with high-speed digital circuitry. It also provides an
LVDS synchronization input that enables data realign-
ment and reframing. The MAX3885 is available in the
extended temperature range (-40°C to +85°C) in a 64-
pin TQFP package.
Pin Configuration appears at end of data sheet.
