The MAX3680/MAX3680A deserializer is ideal for con-
verting 622Mbps serial data to 8-bit-wide, 77Mbps par-
allel data in ATM and SDH/SONET applications.
Operating from a single +3.3V supply, this device
accepts PECL serial clock and data inputs, and deliv-
ers TTL clock and data outputs. The MAX3680 also pro-
vides 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.
