Three modes of operation may be effected by applying to this input a logic high (VDD), logic low (GNDD), or an 8-bit serial word, depending on the logic states of CA and F1i. Functions controlled are: powerdown, filter gain adjust, loopback, chip testing, SD outputs. Data ST-BUS In accepts the incoming 8-bit PCM word. Input is TTL-compatible. Clock Input is a TTL-compatible 2.048 MHz clock. Data ST-BUS Out is a three-state digital output driving the PCM bus with the outgoing 8-bit PCM word. Positive power Supply (+5 V). Synchronization Input is an active low digital input enabling (in conjunction with CA) the PCM input, PCM output and digital control input. It is internally sampled on every positive edge of the clock, C2i, and provid.
