PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

TIOHM

Input

Transmit Input Overhead Mask (TIOHM). TIOHM

indicates the position of overhead bits in the

transmission system stream, TDAT. TIOHM is

delayed internally to produce the TOHM output.

When configured for operation over a DS1, a DS3,

an E1, or an E3 transmission system sublayer,

TIOHM is not required, and should be set to logic 0.

When configured for other transmission systems,

TIOHM is set to logic 1 for each overhead bit

position. TIOHM is set to logic 0 if the transmission

system contains no overhead bits. TIOHM is

sampled on the rising edge of TICLK.

TCLK

Output

Transmit Output Clock (TCLK). TCLK provides

the transmit direction timing. TCLK is a buffered

version of TICLK and can be enabled to update the

TPOS/TDAT and TNEG/TOHM outputs on its rising

or falling edge.
