5 / 96 page ELECTRONICS S5D0127X01 Data Sheet MULTIMEDIA VIDEO PAGE 5 OF 96 Modified on May/04/2000 EVAV(OENC1) 4 I/O Valid line flag. Polarity is programmable. Active when output video line is valid. During reset, the pin is an input and the logic state of this pin is latched into the OENC[1]register bit. Use a 10 k Ω resistor for pull-up or pull-down. ODD 22 O Odd field flag. Polarity is programmable. Active for fields 1 and 3. PID 17 O PAL ID flag. High for phase alternating line. OEN 15 I Digital video data, timing and clock output 3-state control. CK 18 I/O Pixel clock. In normal decoding mode, this is an output. When the EXV port is used as an input, this can be programmed as an input pixel clock. CK2 21 O Pixel output clock (rate is one half of CK) aligned to HAV signal. CCDAT 73 O Sliced VBI data output. Data can be from Closed Caption, Teletext, Intercast, or WSS type encoded data. CCEN 74 O When high, this pin indicates that valid VBI data is being clocked out at the CCDAT pin or at the digital video output. MULTI-PURPOSE I/O PORTS AND TEST ENABLE PORTA 58 I/O Multi-purpose I/O port. SCH(PORTB) 24 I/O Multi-purpose I/O port. TESTEN 57 I When tied to VDD, the chip is put into the test mode. For normal use, this pin should be connected to VSS. TEST 96 I When tied to VDD, the chip is put into the test mode. For normal use, this pin should be connected to VSS. REFERENCE AND COMPENSATION VRT 77 I/O ADC VRT compensation (requires an external 0.1 µF capacitor connected to VSS). VRB 78 I/O ADC VRB compensation (requires an external 0.1 µF capacitor connected to VSS). COMP2 97 I/O Internal 1.3 V reference (requires an external 0.1 µF capacitor connected to VSS). HOST INTERFACE SCLK 75 I Serial clock for IIC host interface. SDAT 72 I/O Serial data for IIC host interface. AEX0 - AEX1 69 - 70 I Device ID selection for IIC host interface.
