3 / 19 page PIN EXPLANATIONS Pin No. Pin Name Applied Voltage (V) Pin Voltage (V) Note Function and Application Internal Equivalent Circuit 1 VCC 4.5 to 5.5 − Power supply pin. This pin should be externally equipped with bypass capacitor to minimize ground impedance. ⎯⎯⎯ 2 INPUT1 − 1.29 Signal input pins to AGC amplifier. This pin should be coupled with capacitor for DC cut. 3 INPUT2 − 1.29 AGC Control 1 2 3 5 4 VAGC 0 to VCC − Gain control pin. This pin’s bias govern the AGC output level. Minimum Gain at VAGC : 0 to 0.5 V Maximum Gain at VAGC : 3 to 3.5 V Recommended to use AGC voltage with externally resister (example: 1 k Ω). AGC Amp. 1 4 5 5 GND2 0 − Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as possible. ⎯⎯⎯ 6 OUTPUT2 − 2.28 Signal output pins of video amplifier. This pin should be coupled with capacitor for DC cut. 7 OUTPUT1 − 2.28 1 7 6 8 8 GND1 0 − Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as possible. All ground pins must be connected together with wide ground pattern to decrease impedance difference. ⎯⎯⎯ Note Pin voltage is measured at VCC = 5.0 V. Data Sheet PU10171EJ03V0DS 3 µPC3221GV |
