Signal description

 

 

 

 

RX_DATA[0]

25

I

RECEIVE DATA: Byte-wide STS-3c data input stream.

RX_DATA[1]

26

 

RX_DATA [7] is the MSB, and RX_DATA [0] the LSB.

RX_DATA[2]

27

 

Data is sampled on the rising edge of RX_SONETCLK.

RX_DATA[3]

28

 

 

RX_DATA[4]

29

 

 

RX_DATA[5]

32

 

 

RX_DATA[6]

33

 

 

RX_DATA[7]

34

 

 

 

 

 

 

RX_FRAME_IN

23

I

RECEIVE FRAME INDICATOR: Frame position indication signal is

 

 

 

active high and indicates the SONET frame position on the RX_

 

 

 

DATA [7:0] bus. Sampled on the rising edge of RX_SONETCLK.

 

 

 

Only used when RX_FRAME_INH is set, otherwise tie this pin low.

RX_LAIS_OUT

153

O

RECEIVE LINE ALARM INDICATION SIGNAL OUTPUT:

 

 

 

Receive line alarm indication signal will be set high if a binary

 

 

 

“111” pattern is received for the number of consecutive frames

 

 

 

programmed into the K2_CONSEC register. RX_LAIS_OUT will

 

 

 

be cleared if a binary “111” pattern is not received for the

 

 

 

number of consecutive frames programmed into the

 

 

 

K2_CONSEC register.

 

 

 

 

RX_LOF_OUT

149

O

RECEIVE LOSS OF FRAME OUTPUT:

 

 

 

RX_LOF_OUT is set high when there is a loss of frame indication.

 

 

 

If RX_OOF_OUT is active continuously for 24 consecutive frames

 

 

 

(3 ms), the RX_LOF bit is set high. Once RX_LOF is set, it remains

 

 

 

high until RX_OOF_OUT is inactive continuously for 3 ms.

RX_LOS

147

I

RECEIVE LOSS OF SIGNAL: RX_LOS should be used to indicate

 

 

 

to the framer that there is no signal present from the optical

 

 

 

receiver. The signal’s default is active high, but can be set to

 

 

 

active low by programming RX_LOS_LEVEL = 1.

RX_OOF_OUT

152

O

RECEIVE OUT OF FRAME OUTPUT: RX_OOF_OUT is set high when

 

 

 

there is an out of frame indication. An out of frame condition occurs

 

 

 

when five consecutive erroneous framing patterns specified

 

 

 

in the A1 or A2 bytes have been received.

 

 

 

 

RX_SONETCLK

24

I

RECEIVE SONET CLOCK: RX_SONETCLK is the receive

 

 

 

input clock from the line side, and provides timing for the

 

 

 

receive data bus and frame position indication inputs.

 

 

 

This clock should be 19.44 MHz ± 20 ppm.

 

 

 

 

TX_DATA[0]

145

O

TRANSMIT DATA: Byte-wide STS-3c data output stream.

TX_DATA[1]

144

 

TX_DATA [7] is the MSB, TX_DATA [0] is the LSB. Data is

TX_DATA[2]

143

 

updated on the rising edge of TX_SONETCLK.

TX_DATA[3]

138

 

 

TX_DATA[4]

137

 

 

TX_DATA[5]

136

 

 

TX_DATA[6]

135

 

 

TX_DATA[7]

134
