SDH/SONET STM16/OC48 multiplexer OQ2535HP

FEATURES

• Normal and loop (test) modes

• 3.3 V TTL compatible data inputs

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

outputs

• 5 V TTL clock output (low speed interface)

• High input sensitivity (100 mV for the high speed clock

GENERAL DESCRIPTION

The OQ2535HP is a 32-channel multiplexer intended for
use inSTM16/OC48 applications. It combines data from a
total of 32 × 78 Mbits/s input channels onto a single

2.5 Gbits/s output channel. It features 3.3 V TTL data
inputs and a 5 V TTL clock output at the low speed
interface, and CML compatible inputs and outputs at the
high speed interface.

input)

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

“IEEE Std 1149.1-1990”

• Low power dissipation (typically 1.65 W).
