Overview

  • Single +3.3V Supply
  • 155Mbps (4-bit-wide) Parallel to 622Mbps Serial Conversion
  • Clock Synthesis for 622Mbps
  • 215mW Power
  • Multiple Clock Reference Frequencies (155.52MHz, 77.76MHz, 51.84MHz, 38.88MHz)
  • LVDS Parallel Clock and Data Inputs
  • Differential 3.3V PECL Serial-Data Output

The MAX3693 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 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.

Applications

  • 622Mbps ATM/SONET Access Nodes
  • 622Mbps SDH/SONET Transmission Systems
  • Add/Drop Multiplexers
  • Digital Cross-Connects
