DATA SHEET FE ATURE S · automatic cable equalization · fully compatible with SMPTE 259M · typically equalizes greater than 350m of high quality cable at 270Mb/s · signal strength indicator · output data muting when input data is lost · output 'eye' monitor (OEM) with large signal amplitude and power down option · low power: 240mW at 5V · 14 pin SOIC package · programmable output data squelch for max cable length limiting · carrier detect with programmable threshold level · serial data output "High Z" select to allow muxing of EQ inputs APP LI CATI O N S Front-end cable equalization for digital video systems; Input equalization for serial digital distribution amplifiers, routers, production switchers and other receiving equipment. D E S C R I P TI O N The GS9024 is a high performance automatic cable equalizer designed for serial digital data rates from 143Mb/s to 540Mb/s. The GS9024 receives either single-ended or differential serial data and outputs equalized differential signals at PECL levels (800mV). The GS9024 provides up to 40dB of gain at 200MHz which will typically result in equalization of greater than 350m at 270Mb/s of Belden 8281 cable. The GS9024 incorporates an analog signal strength indicator/carrier detect (SSI/CD) output indicating both the presence of a carrier and the amount of equalization applied to the signal. Optional external resistors allow the carrier detect threshold level to be customized to the user's requirement. The GS9024 also features selectable High Z serial data outputs eliminating the need for input muxing circuitry in routers. In addition, the GS9024 provides an 'Output Eye Monitor' (OEM) which allows the verification of signal integrity after equalization, prior to reslicing. The GS9024 operates from a single +5V or -5V power supply and consumes only 240mW of power. Packaged in a small 14 pin SOIC, the GS9024 is ideal for router applications where high density component placement is required. ORDERING O RDE RI N G INFORMATION
