Description
CSTi
Control ST-BUS In
is a TTL-compatible digital input used to control the function of the filter/codec.
Three modes of operation may be effected by applying to this input a logic high (V
DD
), 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.
DSTi
Data ST-BUS In
accepts the incoming 8-bit PCM word. Input is TTL-compatible.
C2i
Clock Input
is a
TTL-compatible 2.048 MHz clock.
DSTo
Data ST-BUS Out
is a three-state digital output driving the PCM bus with the outgoing 8-bit PCM
word.
V
DD
F1i
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 provides frame and channel synchronization.
CA
Control Address
is a three-level digital input which enables PCM input and output and determines
into which control register (A or B) the serial data, presented to CSTi, is stored.
SD3
System Drive Output
is an
open drain output of an N-channel transistor which has its source tied to
GNDA. Inactive state is open circuit.
System Drive Outputs
are
open drain outputs of N-channel transistors which have their source tied
to GNDD. Inactive state is open circuit.
System Drive Outputs
are
“Totempole“ CMOS outputs switching between GNDD and V
DD
. Inactive
state is logic low.

Voice Transmit
is the
