+3.3V, 622Mbps, SDH/SONET
1:8 Deserializer with TTL Outputs
_________________General Description
The MAX3680 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. It also provides a TTL synchroniza-
tion input that enables data realignment and reframing.
The MAX3680 is available in the extended-industrial
temperature range (-40°C to +85°C), in a 28-pin SSOP
package.
