Product Summary

The MAX3890ECB is a serializer. It is ideal for converting 16-bitwide, 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 loop back data output is provided to facilitate system diagnostic testing. The MAX3890ECB is available in the extended temperature range (-40℃ to +85℃) in a 64-pin TQFP exposed paddle (EP) package. The applications of the MAX3890ECB include 2.5Gbps SDH/SONET Transmission Systems, 2.5Gbps ATM/SONET Access Nodes, Add/Drop Multiplexers, Digital Cross-Connects, and ATM Backplanes.
