Pin Name

Type

No.

Function

When the byte serial receive interface is

selected (RSER=0), the FPOS/MLT input

selects the frame byte position in the SONET

frame indicated by the FPIN input. When

FPOS/MLT is tied high, a pulse on FPIN marks

the third A2 framing byte position on the

PIN[7:0] bus. When FPOS/MLT is tied low, a

pulse on FPIN marks the first synchronous

payload envelope byte position after the three

C1 bytes on PIN[7:0].

When the bit serial transmit interface is

selected (TSER=1), the FPOS/MLT input

selects MLT-3 encoding of the transmit stream.

When FPOS/MLT is tied high, an MLT-3

encoded data stream is transmitted on the

TXCO+/- and TXD+/- outputs. When

FPOS/MLT is tied low, 155 Mbit/s clock and

data are inserted on the TXCO+/- and TXD+/-

outputs.

FPIN

Input

157

The active high framing position input (FPIN)

signal indicates the SONET frame position on

the PIN[7:0] bus. The byte position indicated

by FPIN is selected by the FPOS/MLT input as

described above. FPIN is sampled on the

rising edge of PICLK.

OOF

Output

The out of frame (OOF) signal is high while the

S/UNI is out of frame. OOF is low while the

S/UNI is in-frame. An out of frame occurs

when 4 consecutive errored framing patterns

(A1 and A2 bytes) have been received. OOF

is intended to be used to enable an upstream

framing pattern detector to search for the

framing pattern when the byte serial interface

is selected. This alarm indication is also

available via register access. OOF is updated

on the falling edge of RCLK.
