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.
