While there are no plans to discontinue the GS9004D, Gennum has developed a successor product with improved features and performance called the GS9024. The GS9024 is recommended for new designs. This device features DC restoration to pass the Pathological Test Signals and fully automatic equalization in order to meet the SMPTE 259M Serial Interface Standard. The DATA and DATA outputs typically deliver 800 mV (p- p) equalized signals into 50 Ω loads (to V TT ). These signals can be used to feed cable driver circuits for Serial Distribution Amplifier applications. This device also incorporates an analog signal strength indicator (SSI) which provides a 0.5 V to 0 V output relative to V CC, indicating the amount of equalization being applied to the signal. The GS9004D features an OUTPUT 'EYE' MONITOR (OEM), which allows verification of signal integrity after equalization, prior to reslicing. Operating with a single +5 or -5 volt supply, the GS9004D typically draws 52 mA of current. ORDERING INFORMATION APPLICATIONS • Front-end cable equalization for digital video systems • Input equalization for serial digital distribution amplifiers, routers, production switchers and other receiving equipment Document No. 32486 - 0 GENNUM CORPORATION P.O.
