Serial Data in (input): A TTL compatible digital input. The 8-bit serial input enables the

drivers. See Table 1 and Figure 3b.

Voltage Reference (Input) +2.5V for the internal codec.

Data in (Input). A TTL compatible digital input which accepts the 8-bit PCM word from the

incoming PCM bus.

Clock input (input). A TTl compatible digital input which accepts the 2048 kHz clock.

Data Out (Output) A three state TTL compatible digital output which drives the 8-bit PCM

word to the outgoing PCM bus.

Synchronization input (Input). A TTL compatible, active low digital output input enabling

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. See fig

3a.

Internal Connection.

Gain setting (Input). A logic ‘0’ at this input will set the receiving gain to -7.0dB and a logic

‘1’ will set the receiving gain to -3.5dB. If this pin is left open, the receiving gain can be set

by SDi, bit 2.

Internal Connection.

Serial Data (Output). A TTL compatible output coming from the SDi, bit 7. Bit inverted.

Serial Data (Output). A TTL compatible output coming from the SDi, bit 6. Bit inverted.

Serial Data (Output). A TTL compatible output coming from the SDi, bit 5. Bit inverted.

Internal Connection.

Relay Positive Supply Voltage. Normally +5V. Connects to the relay coil and the relay

supply voltage.

Relay Ground. Return path for relay supply voltage.

Relay Driver 2 (Output). Connects to a user provided external relay coil. A logic ‘0’

from the SDi, bit 1 will activate this driver. This relay driver is typically used for system

in-test.

Relay Driver 3 (Output). Connects to a user provided external relay coil. A logic ‘0’

from the SDi, bit 4 will activate this driver. This relay driver is typically used for system

in-test.

Relay Driver 1 (Output). Connects to a user provided external relay coil. A logic ‘0’ from

the SDi, bit 0 will activate this driver. This relay driver is typically used for ringing.
