• Manufacturer Part Number: ak4141
• Description: Nicam/a2/eia-j Digital Stereo Decoder
• Manufacturer: AKM Semiconductor, Inc.

2. TDM mode: TDM bit = “1”
MS0952-E-00
The TDM bits = “1” set the AK4141 audio serial interface format to the TDM mode. The eight channel serial data
(SDTI1/2/3 and SDTI4 at non-SRC mode) is input through the SDTI1 pin. The six channel serial data is output through
the SDTO1 pin. The SDTI2/3/4/5 pins are not used for TDM input and the SDTO2/3 pins outputs “L”.
