PIN DESCRIPTION Table 1
PIN
SYMBOL
TYPE
DESCRIPTION
1TCLK
I
Transmit Clock. 1.544 MHz primary clock.
2TSER
I
Transmit Serial Data. Transmit NRZ serial data, sampled on the
falling edge of TCLK.
3TCHCLK
O
Transmit Channel Clock. 192 kHz clock which pulses high during
the LSB of each channel. Useful for parallel-to-serial conversion of
channel data, locating robbed-bit signaling bits, and for blocking
clocks in DDS applications. See Section 13 for timing details.
4
5
TPOS
TNEG
O
Transmit Bipolar Data. Updated on rising edge of TCLK.
6-13
AD0-AD7
I/O
Address/Data Bus. An 8-bit multiplexed address/data bus.
14
BTS
I
Bus Type Select. Strap high to select Motorola bus timing; strap
low to select Intel bus timing. This pin controls the function of
RD
(DS), ALE(AS), and WR (R/ W ) pins. If BTS=1, then these pins
assume the function listed in parentheses ().
15
RD
(DS)
I
Read Input (Data Strobe).
16
CS
I
Chip Select. Must be low to read or write the port.
17
ALE(AS)
I
Address Latch Enable (Address Strobe). A positive-going edge
serves to demultiplex the bus.
18
WR
(R/ W )
I
Write Input (Read/Write).
19
RLINK
O
Receive Link Data. Updated with either FDL data (ESF) or Fs-bits
(D4) or Z-bits (ZBTSI) one RCLK before the start of a frame. See
Section 13 for timing details.
20
VSS
-
Signal Ground. 0.0 volts.
21
RLCLK
O
Receive Link Clock. 192 kHz clock which pulses high during the
LSB of each channel. Useful for parallel-to-serial conversion of
channel data, locating robbed-bit signaling bits, and for blocking
clocks in DDS applications. See Section 13 for timing details.
22
RCLK
I
Receive Clock. 1.544 MHz primary clock.
