Transmit Clock. 1.544 MHz primary clock.
Transmit Serial Data. Transmit NRZ serial data, sampled on the
falling edge of TCLK.
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.
Transmit Bipolar Data. Updated on rising edge of TCLK.
Address/Data Bus. An 8-bit multiplexed address/data bus.
Bus Type Select. Strap high to select Motorola bus timing; strap
low to select Intel bus timing. This pin controls the function of
assume the function listed in parentheses ().
Read Input (Data Strobe).
Chip Select. Must be low to read or write the port.
Address Latch Enable (Address Strobe). A positive-going edge
serves to demultiplex the bus.
Write Input (Read/Write).
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.
Signal Ground. 0.0 volts.
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.
Receive Clock. 1.544 MHz primary clock.
