SDH/SONET STM16/OC48 multiplexer
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 input) Boundary Scan Test (BST) at low speed interface, in accordance with “IEEE Std 1149.1-1990” Low power dissipation (typically 1.65 W). ORDERING INFORMATION TYPE NUMBER OQ2535HP PACKAGE NAME HLQFP100 DESCRIPTION plastic heat-dissipating low profile quad flat package; 100 leads; body 14 × 14 × 1.4 mm GENERAL DESCRIPTION
OQ2535HP
The OQ2535HP is a 32-channel multiplexer intended for use in STM16/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.
