MT9126
Preliminary Information
8-36
Notes:
All unused inputs should be connected to logic low or high unless otherwise stated. All outputs should be left open circuit when not used.
All inputs have TTL compatible logic levels except for MCLK which has CMOS compatible logic levels and PWRDN which has Schmitt
trigger compatible logic levels.
All outputs are CMOS with CMOS logic levels (See DC Electrical Characteristics).

ADPCMi
Serial ADPCM Stream ( Input).
128 kbit/s to 4096 kbit/s serial ADPCM word input
stream. Data bits are clocked in on falling edge of BCLK in SSI mode and clocked in on
the 3/4 bit edge of MCLK in ST-BUS mode.
24
ADPCMo
Serial ADPCM Stream (Output).
128 kbit/s to 4096 kbit/s serial ADPCM word output
stream. Data bits are clocked out by rising edge of BCLK in SSI mode and clocked out by
MCLK divided by two in ST-BUS mode.
