DESCRIPTION

The GS1532 is a multi-standard serializer with an integrated

cable driver. When used in conjunction with the GO1525

Voltage Controlled Oscillator, a transmit solution can be

realized for HD-SDI, SD-SDI and DVB-ASI applications.

In addition to serializing the input, the GS1532 performs

NRZ-to-NRZI encoding and scrambling as per SMPTE

292M/259M-C when operating in SMPTE mode. When

operating in DVB-ASI mode, the device will insert K28.5

sync characters and 8b/10b encode the data prior to

serialization.

Parallel data inputs are provided for 10-bit multiplexed or

20-bit demultiplexed formats at both HD and SD signal

rates. An appropriate parallel clock input signal is also

required.

The integrated cable driver features an output mute on loss

of parallel clock, high impedance mode, adjustable signal

swing, and automatic dual slew rate selection depending

on HD/SD operational requirements.

The GS1532 also includes a range of data processing

functions including automatic standards detection and EDH

support. The device can also insert TRS signals, calculate

and insert line numbers and CRC鈥檚, re-map illegal code

words and insert SMPTE 352M payload identifier packets.

All processing features are optional and may be

enabled/disabled via external control pin(s) and/or host

interface programming.
