LVDS Serializer 0.4V 64-Pin TQFP EP T/R

The MAX3890 serializer is ideal for converting 16-bit-wide, 155Mbps parallel data to 2.5Gbps 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 PECL serial data and clock outputs. A fully integrated PLL synthesizes an internal 2.5GHz serial clock from a 155.52MHz, 77.76MHz, 51.84MHz, or 38.88MHz reference clock. A loopback data output is provided to facilitate system diagnostic testing. The MAX3890 is available in the extended temperature range (-40°C to +85°C) in a 64-pin TQFP exposed- paddle (EP) package.
