Maxim MAX3693ECJ Datasheet

General Description

The MAX3693 serializer is ideal for converting 4-bit­wide, 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 deliv­ers a 3.3V PECL serial-data output. A fully integrated
PLL synthesizes an internal 622Mbps serial clock from
a 155.52MHz, 77.76MHz, 51.84MHz, or 38.88MHz ref­erence clock.

The MAX3693 is available in the extended temperature
range (-40°C to +85°C), in a 32-pin TQFP package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
