GENLINX II GS9021  
EDH Coprocessor  
DATA SHEET  
FEATURES  
DESCRIPTION  
The GS9021 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 GS9021 is primarily used on the  
transmit end of the SDI interface. The GS9021 provides  
EDH insertion and extraction for 4ƒsc NTSC, 4ƒsc PAL and  
all component PAL and NTSC standards including 4:2:2  
(13.5MHz and 18MHz luminance sampling), and 4:4:4:4.  
• Error Detection and Handling (EDH) according to  
SMPTE RP-165  
• EDH insertion and extraction in one device  
• auto-standard operation with override via host  
interface  
• noise immune extraction of HVF timing signals  
• TRS insertion/correction and ANC header correction  
for all standards  
The GS9021 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.  
• ITU-R-601 output clipping for active picture area  
• selectable I²C interface or 8-bit parallel port for access  
to EDH flags and device configuration bits  
• all error flags available on dedicated output pins  
• 24-bit Errored Field counter  
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.  
• BYPASS mode to bypass EDH insertion/updating  
• dynamic blanking control input  
• 8-bit or 10-bit compatibility  
• up to 54MHz operating frequency  
• seamless flag-mapping with GS9020 serial digital  
video input processor  
• 64 pin LQFP  
APPLICATIONS  
ORDERING INFORMATION  
EDH processing for SMPTE 259M serial digital interfaces for  
composite and component standards including 4:4:4:4 at  
540Mb/s; Noise immune digital sync and timing generation.  
Source, destination, distribution and test equipment;  
General purpose, TRS formatted, blank video stream
