DVDD0 - Digital supply, PIN 40Q, 2L
Digital +5V supply.
DVDD1 - Digital supply, PIN 39Q, 1L
Digital +5V supply.
PGND0 - Speaker-driver ground, PIN 18Q, 24L
Speaker driver ground.
PGND1 - Speaker-driver ground, PIN 22Q, 28L
Speaker driver ground.
PVDD - Speaker-driver supply, PIN 20Q, 26L
Speaker-driver +5V supply.
Analog I/O
MICIN - ADC input, PIN 28Q, 34L
Audio analog input.
SPKROUTN - DAC inverted output, PIN 19Q, 25L
Negative differential speaker-driver output. The voltage on SPKROUTN will decrease if the
DAC value is increased.
SPKROUTP - DAC output, PIN 21Q, 27L
Positive differential speaker-driver output. The voltage on SPKROUTP will increase if the
DAC value is increased.
VCM - Voltage reference common out, PIN 24Q, 30L
No time-varying loads should be attached to VCM. Output voltage is about 1V into a load of
not less than 100k
. Must be connected to AGND0 via a 1
μ
F and a 0.1
μ
F capacitors.
Connections should be made with short, fat traces.
VREF - Voltage reference bypass out, PIN 25Q, 31L
Voltage reference used internal to the CS6403. Must be connected to AGND0 via a 1
μ
F and a
0.1
μ
F capacitors. Connections should be made with short, fat traces. No external loads should
be connected to VREF.
Reserved
RESERVED0 - PIN 14Q, 20L
Must be grounded in normal operation.
RESERVED1 - PIN 10Q, 16L
Must be held high in normal operation.
