Philips Semiconductors Product specification

SDH/SONET STM16/OC48 demultiplexer OQ2536HP

FEATURES

• Normal and loop (test) modes

• 1.2 V GTL (Gunning Transceiver Logic) level compatible

data and clock outputs (low speed interface)

• Differential CML (Current-Mode Logic) data and clock
inputs

• High input sensitivity (100 mV for the high speed inputs)

• Boundary Scan Test (BST) at low speed interface, in

accordance with

“IEEE Std 1149.1-1990”

• Low power dissipation (typically 1.45 W).

DESCRIPTION

The OQ2536HP is a 32-channel demultiplexer intended
for use in STM16/OC48 applications. It demultiplexes a
single 2.5 Gbits/s input channel to 32 × 78 Mbits/s output
channels. The data and clock outputs on the low speed
interface are GTL compatible, while the high speed data
and clock inputs are CML compatible.
