GS1574A

Description


The GS1574A is a second-generation high-speed BiCMOS integrated circuit designed to equalize and restore signals received over 75Ohm co-axial cable.

The GS1574A is designed to support SMPTE 292M and SMPTE 259M, and is optimized for performance at 270Mb/s and 1.485Gb/s.

The GS1574A features DC restoration to compensate for the DC content of SMPTE pathological test patterns.

A voltage programmable mute threshold (MCLADJ) is included to allow muting of the GS1574A output when an approximate selected cable length is reached for SMPTE 259M signals. This feature allows the GS1574A to distinguish between low amplitude SD-SDI signals and noise at the input of the device. The serial digital outputs of the GS1574A may be forced to a mute state by applying a voltage to the MUTE pin.

Power consumption is typically 215mW using a 3.3V power supply. The GS1574A is lead-free, and the encapsulation compound does not contain halogenated flame retardant.

This component and all homogeneous subcomponents are RoHS compliant.
