QUINT DIFFERENTIAL LINE RECEIVER FEATURES SY10E116 SY100E116 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-Synergy’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 VBB 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 D3 Q3 D3 Q3 D4 Q4 D4 Q4 PIN CONFIGURATION VBB VCCO Q2 Q4 D2 Q4 Q2 25 24 23 22 21 20 19 D3 26 18 Q3 D2 27 17 Q3 D2 VEE VBB 28 16 VCC 15 14 Q2 Q2 D0 3 13 VCCO 4 12 Q1 D0 PLCC TOP VIEW J28-1 1 2 10 11 5 6 7 8 9 Q0 VCCO D2 VCCO Q1 D4 D1 Q0 Q1 VCCO D1 D3 Q0 D4 D0 D1 Q0 D1 D0 Pin Function D0, D0-D4, D4 Differential Input Pairs Q0, Q0-Q4, Q4 Differential Output Pairs VBB Reference Voltage Output VCCO VCC to Output Q1 PIN NAMES Rev.: E 1 Amendment: /0 Issue Date: November, 1998 SY10E116 SY100E116 Micrel LOGIC EQUATION Qn = Dn DC ELECTRICAL CHARACTERISTICS VEE = VEE(Min.) to VEE(Max.); VCC = VCCO = GND TA = –40°C Symbol Parameter Output Reference Voltage 10E 100E VBB IIH Input HIGH Current IEE Power Supply Current 10E 100E VPP (DC) Input Sensitivity(1) (2) Common Mode Range VCMR TA = 0°C TA = +25°C TA = +85°C Min.

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.

Minimum input swing for which AC parameters are guaranteed. 2. Within-device skew is defined as identical transitions on similar paths through a device. 3. Duty cycle skew is defined only for differential operation when the delays are measured from the cross point of the inputs to the cross point of the outputs.
