SMPTE 259M-C Serial Digital Interfaces
DVB-ASI Serial Digital Interfaces
DESCRIPTION
The GS9062 is a dual-standard serializer with an integrated
cable driver. When used in conjunction with the GO1525
Voltage Controlled Oscillator, a transmit solution can be
realized for SD-SDI and DVB-ASI applications.
In addition to serializing the input, the GS9062 performs
NRZ-to-NRZI encoding and scrambling as per SMPTE
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. 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 and adjustable
signal swing.
The GS9062 also includes a range of data processing
functions including automatic standards detection and EDH
support. The device can also insert TRS signals, 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.
