SY10E116 SY100E116 QUINT DIFFERENTIAL LINE RECEIVER Micrel, Inc. FEATURES DESCRIPTION ■ 450ps max. Propagation Delay ■ Extended 100E VEE range of –4.2V to –5.5V The SY10/100E116 are quint differential line receivers designed for use in new, high-performance ECL systems. These devices have emitter-follower outputs and an internally generated reference supply (VBB) for singleended reception. Active current sources combined with Micrel’s ASSET™ technology provide the receivers with excellent common mode noise rejection. The receiver design features clamp circuitry to cause a defined output state if both the inverting and non-inverting inputs are left open; in this case the Q output goes LOW, while the Q output goes HIGH. If both inverting and non-inverting inputs are at equal potential, the receiver does not go to a defined state, but rather shares current in normal differential amplifier fashion, producing output voltage levels midway between HIGH and LOW. The VBB output is intended for use as a reference voltage for single-ended reception of ECL signals to that device only. When using V BB for this purpose, it is recommended that VBB is decoupled to VCC via a 0.01 µF capacitor. For higher bandwidth, please refer to the SY10/100E416 device. ■ VBB output for single-ended reception ■ Fully compatible with industry standard 10KH, 100K I/O levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E116 ■ Available in 28-pin PLCC package BLOCK DIAGRAM D0 Q0 D0 Q0 D1 Q1 D1 Q1 D2 Q2 D2 Q2 D3 Q3 D3 Q3 D4 Q4 D4 Q4 PIN NAMES Pin VBB M9999-032006 [email protected] or (408) 955-1690 SY10E116 SY100E116 Function D0, D0-D4, D4 Differential Input Pairs Q0, Q0-Q4, Q4 Differential Output Pairs VBB Reference Voltage Output VCCO VCC to Output Rev.: H 1 Amendment: /0 Issue Date: March 2006 SY10E116 SY100E116 Micrel, Inc.

VPP is the minimum differential input voltage required to assure full ECL levels are present at the outputs. 2. VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the "HIGH" input is within the VCMR range and the input swing is greater than VPP (min.) and <1V.
