ECL ProTM
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 -40C to +85C 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 EdgeTM 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 1 2, 3 Pin Name NC 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 75k pull-down resistors. Default condition is LOW when left floating. The input signal should be terminated externally. See "Termination Recommendations" section. 100KEP PECL/ECL compatible 2:1 mux select control. See "Mux Select Truth Table." Enable pin includes an intenal 75k pull-down resistor. Default condition is LOW. Negative Power Supply: For PECL/LVPECL connect to ground. Both VEE pins must be connected together, externally on the PCB, for proper operation. 100KEP PECL/ECL compatible differential output. PECL/ECL termination is with a 50 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. Positive Power Supply. All VCC pins must be connected to the same power supply externally. Bypass with 0.1F//0.01F low ESR capacitors.

1. Measured with 750mV input signal, 50% duty cycle. Output swing 400mV. All loading with a 50 to VCC -2.0V. 2. Skew is measured between outputs under identical transitions. 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. 3. The variation in period between adjacent cycles over a random sample of adjacent cycle pairs. tJITTER_CC = tn- tn + 1, where t is the time between rising edges of the output signal. 4. Random jitter is measured with a K28.7 comma detect character pattern, measured at 1.25Gbps and 2.5Gbps. 5. Deterministic jitter is measured at 1.25Gbps and 2.5Gbps, with both K28.5 and 223-1 PRBS pattern. 6. Total Jitter is defined as an ideal clock input, no more than 1 output edge in 1012 output edges will deviate by more than specifed peak-to-peak jitter value.
