DTA
Data Acknowledgement (Open Drain Output).
This is the data acknowledgement on the
microprocessor interface. This pin is pulled low to signal that the chip has processed the data. A
909
, 1/4 W, resistor is recommended to be used as a pullup.
2-4

STi0-
STi2
ST-BUS Input 0 to 2 (Inputs).
These are the inputs for the 2048 kbit/s ST-BUS input streams.

STi3
ST-BUS Input 3 (Input).
These are the inputs for the 2048 kbit/s ST-BUS input streams.

F0i
Framing 0-Type (Input).
This is the input for the frame synchronization pulse for the 2048 kbit/s
ST-BUS streams. A low on this input causes the internal counter to reset on
the next negative
transition of C4i.
12
14
C4i
4.096 MHz Clock (Input).
ST-BUS bit cell boundaries lie on the alternate falling edges of this clock.
13-15 15-17 A0-A2
Address 0 to 2 (Inputs).
These are the inputs for the address lines on the microprocessor interface.
16-18 19-21 A3-A5
Address 3 to 5 (Inputs).
These are the inputs for the address lines on the microprocessor interface
19
22
DS
Data Strobe (Input).
This is the input for the active high data strobe on the microprocessor interface.
