¡ Semiconductor
SG
MSM7507-01/02/03
Signal ground voltage output.
The output voltage is 1/2 of the power supply voltage.
The output drive current capability is
±300
mA.
This pin provides the SG level for CODEC peripherals.
This output voltage level is undefined during power saving or power down modes.
SGC
Used to generate the signal ground voltage level by connecting a bypass capacitor.
Connect a 0.1
mF
capacitor with excellent high frequency characteristics between the AG pin and
the SGC pin.
ALAW
Control signal input of the companding law selection.
Provides only for the MSM7507-01GS-K/7507-01MS-K. The CODEC will operate in the
m-law
when this pin is at a logic "0" level and the CODEC will operate in the A-law when this pin is at
a logic "1" level. The CODEC operates in the
m-law
if the pin is left open, since the pin is internally
pulled down.
