TI PAN13xx Series – P/N: ENW89829x2KF / ENW89823x2KF / ENW89827x2KF / ENW89842A2KF
New version of data sheet (rev 3.71) is available now. Changes have been made as following:
Added component values for low pass filter on PCM interface.
More information on this changes:
Wording of 11.1 PCM HARDWARE INTERFACE has been changed.
Old:Please contact your sales representative if using the I2S bus over PCM. We strongly recommend adding a low pass filter (series resistor and capacitor to GND) to the bus for better noise suppression. It is not recommended to directly contact the host μController/DSP with the PCM interface.
New:When the I2S bus is used in an application, Panasonic recommends adding a low pass filter (series resistor and capacitor to GND) to the bus for better noise suppression. Connecting the host μController/DSP directly with the module’s I2S interface is not recommended. The suggested low pass filter component values are: 470pf, 120 ohms
