MAX3690
+3.3V, 622Mbps SDH/SONET 8:1 Serializer with Clock Synthesis and TTL Inputs
Low-Power 622Mbps Mux
|
Status
Active: In Production.
Description
The MAX3690 serializer is ideal for converting 8-bit-wide, 77Mbps parallel data to 622Mbps serial data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, this device accepts TTL clock and data inputs, and delivers a 3.3V differential PECL serial-data output. A fully integrated PLL synthesizes an internal 622MHz serial clock from a low-speed crystal reference clock (77.76MHz, 51.84MHz, or 38.88MHz).
The MAX3690 is available in the extended-industrial temperature range (-40°C to +85°C) in a 32-pin TQFP package.
