Transmit Clock Edge
Hardware Mode
This pin is used to select which edge of the transmit clock is used to sample data
on the transmitter on the TPOS/TNEG inputs. By default, data is sampled on the
falling edge. To sample data on the rising edge, this pin must be pulled "High".
Host Mode
μ
PTS[2:1] pins are used to select the type of microprocessor to be used for Host
communication.
"00" = 8051 Intel Asynchronous
"01" = 68K Motorola Asynchronous

:
This pin is internally pulled “Low” with a 50k
resistor.

Transmit Differential Tip Output
TTIP is the positive differential output to the line interface. Along with the TRING
signal, these pins should be coupled to a 1:2 step up transformer for proper opera-
tion.

Transmit Differential Ring Output
TRING is the negative differential output to the line interface. Along with the TTIP
signal, these pins should be coupled to a 1:2 step up transformer for proper opera-
tion.

TPOS/TDATA Input
Transmit digital input pin. In dual rail mode, this pin is the transmit positive data
input. In single rail mode, this pin is the transmit non-return to zero (NRZ) data
input.

Transmitter Negative NRZ Data Input
In dual rail mode, this signal is the negative-rail input data for the transmitter. In
single rail mode, this pin can be left unconnected while in Host mode. However, in
Hardware mode, this pin is used to select the type of encoding/decoding for the E1/
T1 data format. Connecting this pin “Low” enables HDB3 in E1 or B8ZS in T1.
Connecting this pin “High” selects AMI data format.
