14
O
DECODER SHIFT
CLOCK
Decoder
Output which delivers a frequency (DECODER CLOCK + 1 2), synchronous by
the recovered serial data stream.
15
I
TRANSITION SE-
LECT
Decoder
A high input to this pin causes the transition finder to synchronize on every tran-
sition of input data. A low input causes the transition finder to synchronize only
on mid-bit transitions.
16
NC
Blank
Not connected.
17
O
COMMAND SYNC
Decoder
Output of a high from this pin occurs during output of decoded data which was
preceded by a Command (or Status) synchronizing character.
18
I
DECODER PARITY
SELECT
Decoder
An input for parity sense, calling for even parity with input high and odd parity
with input low.
19
I
DECODER RESET
Decoder
A high input to this pin during a rising edge of DECODER SHIFT CLOCK resets
the decoder bit counting logic to a condition ready for a new word.
20
I
COUNT C0
Both
One of five binary inputs which establish the total bit count to be encoded or de-
coded.
21
GROUND
Both
Supply pin.
22
I
MASTER RESET
Both
A high on this pin clears 2:1 counters in both encoder and decoder, and resets
the
÷
6 circuit.
23
I
COUNT C2
Both
See pin 20.
24
O
÷
6 OUT
Encoder
Output from 6:1 divider which is driven by the ENCODER CLOCK.
25
O
BIPOLAR ZERO
OUT
Encoder
An active low output designed to drive the zero or negative sense of a bipolar
line driver.
26
I
OUTPUT INHIBIT
Encoder
A low on this pin forces pin 25 and 27 high, the inactive states.
27
O
BIPOLAR ONE OUT
Encoder
An active low output designed to drive the one or positive sense of a bipolar line
driver.
28
I
SERIAL DATA IN
Encoder
Accepts a serial data stream at a data rate equal to ENCODER SHIFT CLOCK.
29
I
ENCODER ENABLE
Encoder
A high on this pin initiates the encode cycle. (Subject to the preceding cycle be-
ing complete).
30
I
SYNC SELECT
Encoder
Actuates a Command sync for an input high and Data sync for an input low.
31
I
ENCODER PARITY
SELECT
Encoder
Sets transmit parity odd for a high input, even for a low input.
32
O
SEND DATA
Encoder
Is an active high output which enables the external source of serial data.
33
I
SEND CLOCK IN
Encoder
Clock input at a frequency equal to the data rate X2, usually driven by
÷
6 output.
34
O
ENCODER SHIFT
CLOCK
Encoder
Output for shifting data into the Encoder. The Encoder samples SDI pin-28 on
the low-to-high transition of ESC.
35
NC
Blank
Not connected.
36
I
COUNT C3
Both
See pin 20.
37
I
ENCODER CLOCK
Encoder
Input to the 6:1 divider, a frequency equal to 12 times the data rate is usually
input here.
38
O
DATA SYNC
Decoder
Output of a high from this pin occurs during output of decoded data which was
preceded by a data synchronizing character.
39
I
COUNT C4
Both
See pin 20.
40
I
COUNT C1
Both
See pill 20.
