The MAX3691 serializer is ideal for converting 4-bit-
wide, 155Mbps parallel data to 622Mbps serial data in
ATM and SDH/SONET applications. Operating from a
single +3.3V supply, this device accepts low-voltage
differential-signal (LVDS) clock and data inputs for
interfacing with high-speed digital circuitry, and deliv-
ers a 3.3V PECL serial-data output. A fully integrated
PLL synthesizes an internal 622Mbps serial clock from
a 155.52MHz reference clock.
The MAX3691 is available in the extended-industrial
temperature range (-40°C to +85°C), in a 32-pin TQFP
package.
