PCM1772PWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LRCK | bidirectional | Left and right clock that determines which channel is on DATA; its frequency must equal the audio sampling rate, and it is an input from an external device in slave mode or a output generated by the PCM1772 in master mode. |
| 2 | DATA | input | Serial audio data input. |
| 3 | BCK | bidirectional | Serial bit clock that clocks the individual bits of DATA; an input from an external device in slave mode and a BCK output generated by the PCM1772 in master mode. |
| 4 | PD | input | Reset input; when low the device is powered down and all mode control registers are reset to default settings. |
| 5 | AGND1 | power_in | Analog ground that is the return for VCC1. |
| 6 | AGND2 | power_in | Analog ground that is the return for VCC2. |
| 7 | VCOM | passive | Decoupling capacitor connection that requires an external 10-µF capacitor to analog ground for noise filtering, with a nominal voltage of 0.5 VCC2. |
| 8 | VOUTR | output | R-channel analog signal output of the lineout amplifiers. |
| 9 | VOUTL | output | L-channel analog signal output of the lineout amplifiers. |
| 10 | AIN | input | Monaural analog signal mixer input that can be mixed with the output of the L- and R-channel DACs. |
| 11 | VCC2 | power_in | Analog power supply for the lineout amplifier circuits; the voltage level must be the same as VCC1. |
| 12 | VCC1 | power_in | Power supply for all analog circuits except the lineout amplifier; the supply range is 1.6 V to 3.6 V. |
| 13 | MD | input | Mode control port serial data input that controls the operation mode of the PCM1772. |
| 14 | MC | input | Mode control port serial bit clock input that clocks the individual bits of the control data input MD. |
| 15 | MS | input | Mode control port select; the control port is active when this terminal is low. |
| 16 | SCKI | input | System clock input (128, 192, 256 or 384 fS). |
