GS9021ACFU集成電路（IC）的專用IC規(guī)格書PDF中文資料

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 4?sc NTSC, 4?sc PAL and all component PAL and NTSC standards including 4:2:2 (13.5MHz and 18MHz luminance sampling), and 4:4:4:4.

FEATURES

? Error Detection and Handling (EDH) according to SMPTE RP-165

? drop-in replacement for the GS9021

? 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

? 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

? 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
