OCTAL T1/E1/J1 FRAMER/LIU COMBO - HARDWARE DESCRIPTION
TxON

I
Transmitter On
This input pin permits the user to either enable or disable the Trans-
mit 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 out-
put pins will be enabled or disabled by programming the appropriate
channel register. (address 0x0Fn2, bit 3)
N
OTE
:
Whenever the transmitters are turned off, the TTIP and
TRING output pins will be tri-stated.

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

8kHz Clock Output Reference
This pin is an output reference of 8kHz based on the
MCLKIN input. Therefore, the duty cycle of this output is
determined by the time period of the input clock reference.
