MAX3693ECJ+T

Serializers, Deserializers Overview

The MAX3693ECJ+T is a +3.3V, 622Mbps SDH/SONET 4:1 serializer with clock synthesis and LVDS inputs. It converts 4-bit-wide, 155Mbps parallel data to 622Mbps serial data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, it 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 device operates within the extended temperature range of -40°C to +85°C and is housed in a 32-pin TQFP package.
