Product specification
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 DESCRIPTION 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.
VERSION SOT470-1
HLQFP100 plastic heat-dissipating low profile quad flat package; 100 leads; body 14 × 14 × 1.4 mm
