DESCRIPTION
The GS9021A implements error detection and handling
(EDH) according to SMPTE RP-165. Interfacing to the
parallel inputs of either the GS9002, GS9022 or GS9032
serial digital encoders, the GS9021A is primarily used on
the transmit end of the SDI interface. The GS9021A
provides EDH insertion and extraction for 4sc NTSC, 4sc
PAL and all component PAL and NTSC standards including
4:2:2 (13.5MHz and 18MHz luminance sampling), and
4:4:4:4.
The GS9021A generates noise immune timing signals such
as horizontal sync, vertical blanking and field ID. In
addition, TRS-ID correction/insertion and data blanking are
implemented for all standards.
A host interface, configurable as an 8-bit parallel interface
or an I2C (I2C is a registered trademark of Philips) serial
interface allows for communication with a microcontroller.
The interface can be used to read and/or write the
complete set of error flags and override the flag status prior
to re-transmission. A 5-bit flag port provides access to all
error flags on dedicated pins for applications where the
microcontroller is not used. The device automatically
determines the operating standard, but this can be
overridden through the programming interface.
