The external 75 Ω series resistor determines the impedance of the output. The output will drive a 75 Ω load through a 75 Ω coax. 1.0 Vpp (75% Color Saturation), 1.23 Vpp (100% Color Saturation) at the 75 Ω load. 3 Luma S–Video Luminance S–Video output. The external 75 Ω series resistor determines the impedance of the output. The output will drive a 75 Ω load through a 75 Ω coax. 1.0 Vpp with sync (100% output) at the 75 Ω load. 4 Chroma S–Video Chrominance S–Video output. The external 75 Ω series resistor determines the impedance of the output. The output will drive a 75 Ω load through a 75 Ω coax. 885 mVpp (100% output) when at the 75 Ω load. 5 Luma Clamp Luminance Output Clamp storage capacitor. A 0.01 µF capacitor should be connected from this pin to ground. 3.4 Vdc. 6 YIn Luminance input from the delay line. The delayed Luma from Pin 10 is applied at this pin. 500 mVpp of Composite Luma when 100% saturated RGB inputs are applied. 7 Sync In/ Sync Sep Composite Sync input. Negative going sync should be applied at this pin. The input has a threshold of 1.4 V. The peak voltage may not exceed VCC. Minimum voltage should not be less than 0 V. See Figure 2 for input requirements. 8 4x fsc Xtal /4x fsc In Four times Subcarrier Frequency Crystal Oscillator pin. This pin provides for the connection of the oscillator resonant element. Pin may also be driven directly with a 4x subcarrier signal. 300 to 600 mVpp 4x subcarrier input if the pin is being externally driven. Approximately 40 mVpp, if a crystal is being used. 9 3.58/ 4.43 MHz In/PLL Off External Subcarrier Input. This pin provides an input to a Phase Detector and PLL and allows phase–lock of the 4x oscillator to an external subcarrier reference. To disable the PLL, this pin should be grounded. 400 Hz of pull–in and lock–in range is possible with a crystal. 0.10 to 3.0 Vpp (AC coupled) of subcarrier to phase–lock 4x oscillator or grounded to disable the PLL. |
