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
, 1/4W, 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.
5-9
7-11
STi3-
STi7
ST-BUS Input 3 to 7 (Inputs).
These are the inputs for the 2048 kbit/s ST-BUS input
streams.

DD
Power Input.
Positive Supply.
11
13
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-

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.
20
23
R/W
Read or Write (Input).
This is the input for the read/write signal on the microprocessor
interface - high for read, low for write.
21
24
CS
Chip Select (Input).
This is the input for the active low chip select on the microprocessor
interface
