SuperLite Micrel, Inc. SY55855V SuperLite DUAL CML/PECL/LVPECL-to-LVDS TRANSLATOR SY55855V FEATURES Guaranteed f >750MHz over temperature MAX SuperLite 1.5Gbps throughput capability 3.0V to 5.7V power supply DESCRIPTION Guaranteed <700ps propagation delay over temperature The SY55855V is a fully differential, CML/PECL/ Guaranteed <50ps within-device skew over LVPECL-to-LVDS translator. It achieves LVDS signaling temperature up to 1.5Gbps, depending on the distance and the LVDS compatible outputs characteristics of the media and noise coupling sources. Fully differential I/O architecture LVDS is intended to drive 50 impedance transmission line media such as PCB traces, backplanes, or cables. Wide operating temperature range: 40C to +85C SY55855V inputs can be terminated with a single Available in a tiny 10-pin MSOP package resistor between the true and the complement pins of a given input. The SY55855V is a member of Micrels new SuperLite family of high-speed logic devices. This family features very small packaging, high signal integrity, and operation at many different supply voltages.

PIN DESCRIPTION Pin Number Pin Name Pin Function 1, 2 D0, /D0 CML/PECL/LVPECL Input (Differential). This is one of the inputs. It is converted to LVDS onto the Q0 and /Q0 outputs. 3, 4 D1, /D1 CML/PECL/LVPECL Input (Differential). This is the other input. It is converted to LVDS onto the Q1 and /Q1 outputs. 5 GND Ground. 6, 7 /Q1, Q1 LVDS Output (Differential). This is the other LVDS output. It buffers the CML input that appears at D1, /D1. 8, 9 /Q0, Q0 LVDS Output (Differential). This is one LVDS output. It buffers the CML input that appears at D0, /D0. 10 V V CC CC TRUTH TABLE D0 D1 Q0 /Q0 Q1 /Q1 00 0 1 0 1 01 0 1 1 0 10 1 0 0 1 11 1 0 1 0 M9999-110705 2 hbwhelp micrel.com or (408) 955-1690
