MAX3680, MAX3680A
+3.3V, 622Mbps, SDH/SONET 1:8 Deserializer with TTL Outputs
Low-Power 622Mbps Demux
|
Status
Active: In Production.
Description
The MAX3680/MAX3680A deserializer is ideal for converting
622Mbps serial data to 8-bit-wide, 77Mbps 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
TTL clock and data outputs. The MAX3680 also provides
a TTL synchronization input that enables data
realignment and reframing.
The MAX3680/MAX3680A is available in the extended-industrial
temperature range (-40°C to +85°C), in a 28-pin SSOP package.
