M13 MULTIPLEXER/CLEAR CHANNEL DS3 FRAMER IC

REV. P1.0.6

PRELIMINARY

RxDS1Data_14

Receive DS1/E1 Data Output - Channel 14:

This pin outputs either a DS1 or E1 signal from the M12 multiplexer.

Each bit, within the DS1 or E1 data stream is output upon the rising

edge of RxDS1Clk_14.

RxDS1Clk_14

Receive DS1/E1 Clock Output - Channel 14:

This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock

signal to the Terminal Equipment. The XRT72L13 will update the data

on the "RxDS1Data_14" line, upon the rising edge of this signal.

RxDS1Data_13

Receive DS1/E1 Data Output - Channel 13:

This pin outputs either a DS1 or E1 signal from the M12 multiplexer.

Each bit, within the DS1 or E1 data stream is output upon the rising

edge of RxDS1Clk_13.

RxDS1Clk_13

Receive DS1/E1 Clock Output - Channel 13:

This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock

signal to the Terminal Equipment. The XRT72L13 will update the data

on the "RxDS1Data_13" line, upon the rising edge of this signal.

RxDS1Data_12

Receive DS1/E1 Data Output - Channel 12:

This pin outputs either a DS1 or E1 signal from the M12 multiplexer.

Each bit, within the DS1 or E1 data stream is output upon the rising

edge of RxDS1Clk_12.

RxDS1Clk_12

Receive DS1/E1 Clock Output - Channel 12:

This pin outputs either a DS1 (1.544MHz) or an E1 (2.048MHz) clock

signal to the Terminal Equipment. The XRT72L13 will update the data

on the "RxDS1Data_12" line, upon the rising edge of this signal.

RxDS1Data_11

Receive DS1 Data Output - Channel 11:

This pin outputs a DS1 signal from the M12 multiplexer. Each bit,

within the DS1 data stream is output upon the rising edge of

RxDS1Clk_11.

This output pin is inactive if the corresponding M12 DEMUX is de-

multiplexing an ITU-T G.747 data stream.

This pin will output the contents of DS2 channel # 3, if M12 MUX # 3

is bypassed.

RxDS1Clk_11

Receive DS1 Clock Output - Channel 11:

This pin outputs a DS1 (1.544MHz) clock signal to the Terminal

Equipment. The XRT72L13 will update the data on the

"RxDS1Data_11" line, upon the rising edge of this signal.

NOTES:

1. This output pin is inactive if the corresponding M12 DEMUX is

de-multiplexing an ITU-T G.747 data stream.

2. This pin will output a DS2 rate clock signal (6.312MHz) if M12

# 3 is bypassed.

Power Supply Pin

RxDS1Data_10

Receive DS1/E1 Data Output - Channel 10:

This pin outputs either a DS1 or E1 signal from the M12 multiplexer.

Each bit, within the DS1 or E1 data stream is output upon the rising

edge of RxDS1Clk_10.
