FEATURES

DEVICE DESCRIPTION

The GS9015A is a monolithic IC designed to receive SMPTE

259M serial digital video signals. This device performs the

function of data and clock recovery. It interfaces directly with

the

While there are no plans to discontinue the GS9015A, Gennum

has developed a successor product with improved features

and performance called the GS9035.

The GS9035 is

recommended for new designs.

The VCO centre frequencies are controlled by external resistors

which can be selected by applying a two bit binary code to the

Standards Select input pins. Alternatively, the GS9015A can

be used with the GS9010A to form an adjustment free reclocker

system.

The GS9015A is packaged in a 28 pin PLCC operating from

a single +5 or -5 volt supply.
