ECL Pro™ SY10EP58V ECL Pro™ SY100EP58V 3.3V/5V 3GHz PECL/ECL 2:1 MULTIPLEXER Micrel, Inc. SY10EP58V SY100EP58V FEATURES ■ 2:1 PECL/ECL multiplexer ■ Guaranteed AC–performance over temperature/voltage • >3GHz fMAX (toggle) • <200ps rise/fall time • <420ps propagation delay (D-to-Q) ■ Low jitter performance • Random jitter: <1psrms • Deterministic jitter: <15pspp • Total jitter (clock): <1pspp ■ Flexible supply voltage: +3V to +5.5V ■ Wide operating temperature range: –40°C to +85°C ■ Available in 8-pin MSOP and SOIC packages ECL Pro™ DESCRIPTION The SY10/100EP58V are 3.3V/5V, precision, high-speed, 2:1 multiplexers. Both devices are pin-for-pin, plug-in replacements for the MC10/100EP58D/DT in 8-pin SOIC and 6-pin TSSOP (MSOP) packages. The signal-path inputs (Da and Db) are single-ended PECL/ECL compatible, and can accept a signal swing as low as 150mV. All I/O pins are 10K/100K EP ECL/PECL compatible. AC–performance is guaranteed over the industrial –40°C to +85°C temperature range and 3.0V to 5.5V supply voltage range. Maximum throughput (fMAX) is guaranteed to be 3GHz with a differential output swing ≥400mV. In addition, these multiplexers are optimized for low-jitter applications. The SY10EP58V and SY100EP58V are designed to operate in either ECL/PECL or PECL/LVPECL mode. The SY100EP58V is internally temperature compensated, thus is 100K EP ECL/PECL compatible—I/O logic levels remain constant over temperature. The SY10/100EP58V is part of Micrel's high-speed, Precision Edge™ timing and distribution family. For applications that require a differential I/O combination, consult the Micrel website at www.micrel.com, and choose from a comprehensive product line of high-speed, low skew fanout buffers, translators, and clock dividers.

PIN DESCRIPTION Pin Number Pin Name 1 NC 2, 3 Da, Db(1) Pin Function No connect. 100KEP PECL/ECL single-ended input channels a and b. Multiplexing of these inputs are controlled by SEL. The signal inputs include internal 75kΩ pull-down resistors. Default condition is LOW when left floating. The input signal should be terminated externally. See “Termination Recommendations” section. 4 SEL 100KEP PECL/ECL compatible 2:1 mux select control. See “Mux Select Truth Table.” Enable pin includes an intenal 75kΩ pull-down resistor. Default condition is LOW. 5 VEE Negative Power Supply: For PECL/LVPECL connect to ground. Both VEE pins must be connected together, externally on the PCB, for proper operation. 6, 7 /Q, Q 100KEP PECL/ECL compatible differential output. PECL/ECL termination is with a 50Ω resistor to VCC –2V. Unused single-ended outputs must have a balanced load. For AC–coupled applications, the output stage emitter follower must have a DC current path to ground. See “Termination Recommendations” section. 8 VCC Positive Power Supply. All VCC pins must be connected to the same power supply externally. Bypass with 0.1µF//0.01µF low ESR capacitors. Note: 1. If the inputs are AC–coupled, teh outputs Q, and /Q will experience duty cycle distoration because the input levels do not track the internal reference voltage.
