Transmit Data [TDATA].
Sampled on the falling edge of TCLK with data to be clocked through the
transmit side formatter. This pin is normally tied to TESO.
Transmit Positive Data Output [TPOSO].
Updated on the rising edge of TCLKO with the bipolar data
out of the transmit side formatter. Can be programmed to source NRZ data via the Output Data Format
(TCR1.7) control bit. This pin is normally tied to TPOSI.
Transmit Negative Data Output [TNEGO].
Updated on the rising edge of TCLKO with the bipolar
data out of the transmit side formatter. This pin is normally tied to TNEGI.
Transmit Clock Output [TCLKO].
Buffered clock that is used to clock data through the transmit side
formatter (i.e. either TCLK or RCLKO if Loss Of Transmit Clock is enabled and in effect or RCLKI if
remote loopback is enabled). This pin is normally tied to TCLKI.
Transmit Positive Data Input [TPOSI].
Sampled on the falling edge of TCLKI for data to be
transmitted out onto the E1 line. Can be internally connected to TPOSO by tying the LIUC pin high.
Transmit Negative Data Input [TNEGI].
Sampled on the falling edge of TCLKI for data to be
transmitted out onto the E1 line. Can be internally connected to TNEGO by tying the LIUC pin high.
Transmit Clock Input [TCLKI].
Line interface transmit clock. Can be internally connected to TCLKO
by tying the LIUC pin high.
RECEIVE SIDE DIGITAL PINS
Receive Link Data [RLINK].
Updated with the full recovered E1 data stream on the rising edge of
RCLK.
Receive Link Clock [RLCLK].
4 kHz to 20 kHz clock (Sa bits) for the RLINK output. See Section 11
for details.
Receive Clock [RCLK].
2.048 MHz clock that is used to clock data through the receive side framer.
Receive Channel Clock [RCHCLK].
256 kHz clock which pulses high during the LSB of each channel.
Synchronous with RCLK when the receive side elastic store is disabled. Synchronous with RSYSCLK
when the receive side elastic store is enabled. Useful for parallel to serial conversion of channel data.
Receive Channel Block [RCHBLK].
A user-programmable output that can be forced high or low during
any of the 32 E1 channels. Synchronous with RCLK when the receive side elastic store is disabled.
Synchronous with RSYSCLK when the receive side elastic store is enabled. Useful for blocking clocks to
a serial UART or LAPD controller in applications where not all E1 channels are used such as Fractional
E1, 384k bps service, 768k bps, or ISDN-PRI. Also useful for locating individual channels in drop-and-
insert applications, for external per-channel loopback, and for per-channel conditioning. See Section 9 for
details.
Receive Serial Data [RSER].
Received NRZ serial data. Updated on rising edges of RCLK when the
receive side elastic store is disabled. Updated on the rising edges of RSYSCLK when the receive side
elastic store is enabled.
