Transmitter Tip Output
Positive differential transmit output to the line.
Transmitter Ring Output
Negative differential transmit output to the line.
Transmitter Positive Data Input
In dual-rail mode, this signal is the positive-rail input data for the transmitter.
Transmitter Data Input
In single-rail mode, this pin is used as the NRZ input data for the transmitter.
N
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.
Coding Select
In Hardware Mode and with single-rail mode selected, connecting this pin
"Low" enables HDB3 in E1 or B8ZS in T1 encoding and decoding. Connect-
ing this pin "High" selects AMI data format.
N
Transmitter Clock Input
E1 rate at 2.048MHz ± 50ppm
T1 rate at 1.544MHz ± 32ppm
During normal operation, both in Host Mode and Hardware Mode, TCLK is
used for sampling input data at TPOS/TDATA and TNEG/CODES while
MCLK is used as the timing reference for the transmit pulse shaping circuit.
Transmit Clock Edge
In Hardware Mode, with this pin set to a "High", transmit input data is sam-
pled at the rising edge of TCLK. With this pin tied "Low", input data are sam-
pled at the falling edge of TCLK.
N
Transmitter Turn On
In Hardware Mode, setting this pin "High" turns on the Transmit Section. In
this mode, when TXON = “0”, TTIP and TRING driver outputs will be tri-
stated.
In Host Mode, setting bit 5 (TXONCTL) to “1”, in Register 18 (12h), control of
the transmitter output is transferred to the hardware pin TXON.
