DESCRIPTION
29
LI_SDI
O
Serial Port Data for the Line Interface. Connects directly to the
SDI input pin on the line interface. See Sections 12 and 13 for
timing details.
30
LI_CLK
O
Serial Port Clock for the Line Interface. Connects directly to the
SCLK input pin on the line interface. See Sections 12 and 13 for
timing details.
31
LI_ CS
O
Serial Port Chip Select for the Line Interface. Connects directly
to the CS input pin on the line interface. See Sections 12 and 13 for
timing details.
32
33
RCHBLK
TCHBLK
O
Receive/Transmit Channel Block. A user programmable output
that can be forced high or low during any of the 32 E1 channels.
Useful for blocking clocks to a serial UART or LAPD controller in
applications where not all E1 channels are used such as Fractional
E1 or ISDN-PRI. Also useful for locating individual channels in
drop-and-insert applications. See Sections 9 and 13 for details.
34
RLOS/LOTC
O
Receive Loss of Sync/Loss of Transmit Clock. A dual function
output. If TCR2.0=0, then this pin will toggle high when the
synchronizer is searching for the E1 frame and multiframe. If
TCR2.0=1, then this pin will toggle high if the TCLK pin has not
toggled for 5
s.
35
INT2
O
Receive Alarm Interrupt 2. Flags host controller during conditions
defined in Status Register 2. Active low, open drain output.
36
INT1
O
Receive Alarm Interrupt 1. Flags host controller during alarm
conditions defined in Status Register 1. Active low, open drain
output.
37
TLCLK
O
Transmit Link Clock. 4 kHz to 20 kHz demand clock for the
TLINK input. Controlled by TCR2. See Section 13 for timing
details.
38
TLINK
I
Transmit Link Data. If enabled, this pin will be sampled on the
falling edge of TCLK to insert Sa bits. See Section 13 for timing
details.
39
TSYNC
I/O
Transmit Sync. A pulse at this pin will establish either frame or
CAS multiframe boundaries for the DS2143. Via TCR1.1, the
DS2143 can be programmed to output either a frame or multiframe
pulse at this pin. See Section 13 for timing details.
