NAME
PIN
I/O
FUNCTION
SDI
6
I
Serial Data Input. Sampled on rising edge (ICES = 0) or the falling edge
(ICES = 1) of SCLK.
SDO
7
O
Serial Data Output. Valid on the falling edge (OCES = 0) or the rising
edge (OCES = 1) of SCLK.
TCLK
43
I
Transmit Clock. A 2.048 MHz or 1.544 MHz primary clock. Used to
clock data through the transmit side formatter. Can be sourced internally
by MCLK or RCLK. See Common Control Register 1 and Figure 1-3.
TEST
26
I
Tri-State Control. Set high to tri-state all outputs and I/O pins (including
the parallel control port). Set low for normal operation. Useful in board
level testing.
TNEG
42
I
Transmit Negative Data. Sampled on the falling edge (CCR2.1 = 0) or
the rising edge (CCR2.1 = 1) of TCLK for data to be transmitted out onto
the line.
TPOS
41
I
Transmit Positive Data. Sampled on the falling edge (CCR2.1 = 0) or the
rising edge (CCR2.1 = 1) of TCLK for data to be transmitted out onto the
line.
TTIP/TRING
34/37
O
Transmit Tip and Ring . Analog line driver outputs. These pins connect
via a step-up transformer to the line. See Section 5 for details.
VDD
21/36
-
5.0V ±5% Positive Supply
VSM
20
I
Voltage Supply Mode. Should be tied high for 5V operation.
VSS
22/35
