The MAX3681 deserializer is ideal for converting
622Mbps serial data to 4-bit-wide, 155Mbps parallel
data in ATM and SDH/SONET applications. Operating
from a single +3.3V supply, this device accepts PECL
serial clock and data inputs, and delivers low-voltage
differential-signal (LVDS) clock and data outputs for
interfacing with high-speed digital circuitry. It also pro-
vides an LVDS synchronization input that enables data
realignment and reframing.
The MAX3681 is available in the extended-industrial
temperature range (-40°C to +85°C), in a 24-pin SSOP
package.
