Transmit Positive Analog Output (TTIPn):
TTIP is the positive differential output to the line interface. This output pin,
along with the corresponding TRING output pin, function as the Transmit DS1/
E1 output signal drivers for the XRT86VL34 device.
The user is expected to connect this signal and the corresponding TRING out-
put signal to a 1:2 step up transformer for proper operation.
This output pin will be tri-stated whenever the user sets the “TxON” input pin
or register bit (0xnF02, bit 3) to “0”.

purposes.

Transmitter On
This input pin permits the user to either enable or disable the Transmit Output
Driver within the Transmit DS1/E1 LIU Block. If the TxON pin is pulled “Low”,
all 8 Channels are tri-stated. When this pin is pulled ‘High’, turning on or off the
transmitters will be determined by the appropriate channel registers (address
0x0Fn2, bit 3)
LOW
= Disables the Transmit Output Driver within the Transmit DS1/E1 LIU
Block. In this setting, the TTIP and TRING output pins of all 8 channels will be
tri-stated.
HIGH
= Enables the Transmit Output Driver within the Transmit DS1/E1 LIU
Block. In this setting, the corresponding TTIP and TRING output pins will be
enabled or disabled by programming the appropriate channel register.

Master Clock Input:
This pin is used to provide the timing reference for the internal
master clock of the device. The frequency of this clock is pro-
grammable from 8kHz to 16.384MHz in register 0x0FE9.
