5 / 81 page  [AK4635] Rev. 0.6 2007/10 - 5 - PIN/FUNCTION No. Pin Name I/O Function D2 VCOM O Common Voltage Output Pin, 0.45 x AVDD Bias voltage of ADC inputs and DAC outputs. C1 VSS1 - Ground Pin D1 AVDD - Analog Power Supply Pin E2 VCOC O Output Pin for Loop Filter of PLL Circuit This pin should be connected to VSS1 with one resistor and capacitor in series. A2 PDN I Power-Down Mode Pin “H”: Power up, “L”: Power down reset and initialize the control register. AK4635 should always be reset when powered-up. A6 I2C I Control Mode Select Pin “H”:I2C Bus, “L”:3-wire Serial CSN I Chip Select Pin (I2C pin = “L”) B2 SDA I/O Control Data Input/Output Pin (I2C pin = “H”) CCLK I Control Data Clock Pin (I2C pin = “L”) B3 SCL I Control Data Clock Pin (I2C pin = “H”) C3 CDTIO I/O Control Data Input/Output Pin (I2C pin = “L”) This pin should be connected to the ground. (I2C pin = “H”) B4 SDTI I Audio Serial Data Input Pin A5 SDTO O Audio Serial Data Output Pin A3 FCK I/O Frame Clock Pin A4 BICK I/O Audio Serial Data Clock Pin B6 DVDD - Digital Power Supply Pin C6 VSS2 - Ground Pin C4 MCKI I External Master Clock Input Pin B5 MCKO O Master Clock Output Pin E5 SPP O Speaker Amp Positive Output Pin C5 SPN O Speaker Amp Negative Output Pin D6 VSS3 - Ground Pin D5 SVDD - Speaker Amp Power Supply Pin D4 AOUT O Mono Line Output Pin D3 MPI O MIC Power Supply Pin for Microphone MIC I Microphone Input Pin for Single Ended Input (MDIF bit = “0”) E3 MICP I Microphone Positive Input Pin for Differential Input (MDIF bit = “1”) LIN I Line Input Pin for Single Ended Input (MDIF bit = “0”) E4 MICN I Microphone Negative Input Pin for Differential Input (MDIF bit = “1”) E1 VIN I Composite Video Signal Input Pin C2 VOUT O Composite Video Signal Driver Pin A1 VSAG I Composite Video Signal Output Feedback Input Pin E6 NC - No Connection No internal bonding. This pin should be connected to the ground. Note : All input pins except analog input pins (MIC/MICP, LIN/MICN, VIN, VSAG pins) must not be left floating |
