2 / 15 page STA120 2/15 ABSOLUTE MAXIMUM RATINGS PIN CONNECTIONS (Top view) Symbol Parameter Value Unit VD+, VA+ Power Supply Voltage 4 V VIN Input Voltage ( excluding pins 9, 10) -0.3 to VD+ +0.3 V Tamb Ambient Operating Temperature (power applied) -30 to +85 °C Tstg Storage Temperature -40 to 150 °C PINS DESCRIPTION N. Name Description Power Supply 7VD+ Positive Digital Power.Positive supply for the digital section. Nominally 3.3V. 8 DGND Digital Ground.Ground for the digital section. 21 AGND Analog Ground.Ground for the analog section. AGND should be connected to same ground as DGND. 22 VA+ Positive Analog Power.Positive supply for the analog section. Nominally 3.3V. Audio Output Interface 11 FSYNC Frame Sync.Delineates the serial data and may indicate the particular channel, left or right and may be an input or output. The format is based on M0, M1, M2 and M3 pins. 12 SCK Serial Clock.Serial clock for SDATA pin which can be configured (via the M0, M1, M2 and M3 pins) as an input or output and can sample data on the rising or falling edge. As an output, SCK will generate 32 clocks for every audio sample. As an input, 32 SCK periods per audio sample must be provided in all normal modes. 17, 18, 23, 24 M2, M3, M1, M0 Serial Port Mode Selects.Selects the format of Fsync and the sample edge of SCK with respect to SDATA. 26 SDATA Serial Data. Audio data serial output pin.
