8 / 82 page GS2962 3G/HD/SD-SDI Serializer with Complete SMPTE Video Support Data Sheet 48005 - 7 October 2010 8 of 82 1.2 Pin Descriptions Table 1-1: Pin Descriptions Pin Number Name Timing Type Description A1, A2, B1, B2, B3, C1, C2, C3, D1, D2 DIN[19:10] Input PARALLEL DATA BUS Signal levels are LVCMOS / LVTTL compatible. 20-bit mode 20BIT/10BIT = HIGH Data Stream 1/Luma data input in SMPTE mode (SMPTE_BYPASS = HIGH) Data input in data through mode (SMPTE_BYPASS = LOW) 10-bit mode 20BIT/10BIT = LOW Multiplexed Data Stream 1/Luma and Data Stream 2/Chroma data input in SMPTE mode (SMPTE_BYPASS = HIGH) Data input in data through mode (SMPTE_BYPASS = LOW) DVB-ASI data input in DVB-ASI mode (SMPTE_BYPASS = LOW) (DVB_ASI = HIGH) A3 F/DE Synch- ronous with PCLK Input PARALLEL DATA TIMING. Signal levels are LVCMOS / LVTTL compatible. TIM_861 = LOW: Used to indicate the ODD / EVEN field of the video signal when DETECT_TRS is set LOW. The device will set the F bit in all outgoing TRS signals for the entire period that the F input signal is HIGH (IOPROC_EN/DIS must also be HIGH). The F signal should be set HIGH for the entire period of field 2 and should be set LOW for all lines in field 1 and for all lines in progressive scan systems. The F signal is ignored when DETECT_TRS = HIGH. TIM_861 = HIGH: The DE signal is used to indicate the active video period when DETECT_TRS is set LOW. DE is HIGH for active data and LOW for blanking. See Section 4.3 and Section 4.3.2 for timing details. The DE signal is ignored when DETECT_TRS = HIGH. |
