¡ Semiconductor
MSM7717-01/02/03
SG
Signal ground voltage output.
The output voltage is 1/2 of the power supply voltage.
The output drive current capability is ±200 mA.
This pin provides the SG level for CODEC peripherals.
This output voltage level is undefined during power-saving or power-down mode.
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.
Only the MSM7717-01GS-K/7717-01MS-K has this pin. The CODEC will operate in the m-law
when this pin is at a logic "0" level and the CODEC will has this pin 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.
