Micrel, Inc. QUINT DIFFERENTIAL LINE RECEIVER DESCRIPTION FEATURES The SY100S314 offers five differential line receivers with emitter follower outputs, designed for use in high-performance ECL systems. For single-ended operation, the VBB reference voltage is available. In the single-ended mode, the apparent input threshold of the true inputs is 30mV higher than the threshold of the complementary inputs. Common mode rejection of +1.0V is achieved through the use of active current sources. If both the true and complement inputs are at the same potential between VEE and VCC, then the complementary outputs will take on a logic HIGH state. Unlike the other members of the Micrel 300K family, the inputs on this device do not have pull-down resistors. ■ ■ ■ ■ ■ Max. propagation delay of 900ps Differential outputs IEE min. of –60mA Extended supply voltage option: VEE = –4.2V to –5.5V Voltage and temperature compensation for improved noise immunity ■ VBB output for single-ended use ■ More than twice as fast as Fairchild ■ Function and pinout compatible with Fairchild F100K ■ Available in 28-pin PLCC package PIN NAMES BLOCK DIAGRAM M9999-060910 [email protected] or (408) 955-1690 SY100S314 SY100S314 1 Pin Da – De Data Inputs Function Da – De Inverting Data Inputs Oa – Oe Data Outputs Oa – Oe Complementary Data Outputs VEES VEE Substrate VCCA VCCO for ECL Outputs Rev.: I Amendment: /0 Issue Date: June 2010 SY100S314 Micrel, Inc.
