Drop-in compatible with GS2974
Pb-free and RoHS compliant
Applications
SMPTE 424M, SMPTE 292M and SMPTE 259M coaxial
cable serial digital interfaces
Description
The GS2964 is a high-speed BiCMOS integrated circuit
designed to equalize and restore signals received over 75Ω
coaxial cable.
The device is designed to support SMPTE 424M, SMPTE
292M and SMPTE 259M, and is optimized for performance
at 1.485Gb/s and 2.97Gb/s.
The GS2964 features DC restoration to compensate for the
DC content of SMPTE pathological test patterns.
The Carrier Detect output pin (CD
) indicates whether a
valid input signal has been detected. It can be connected
directly to the MUTE pin to mute the output on loss of
carrier.
The equalizing and DC restore stages are disengaged when
the BYPASS pin is HIGH. No equalization occurs in Bypass
mode.
The differential outputs can be DC-coupled to Gennum
3.3V cable drivers and reclockers and to industry-standard
3.3V CML logic.
The GS2964 is footprint and drop-in compatible with
existing GS2974 designs, with no additional application
changes required.
The device is available in a 16-pin, 4mm x 4mm QFN
package.
Power consumption of the GS2964 is typically 150mW.
The GS2964 is Pb-free, and the encapsulation compound
does not contain halogenated flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.
