DESCRIPTION
The SY89208V is a 3.3V/5V precision high-speed 2:1 multiplexer. It is functionally equivalent to the SY100EP58V but in an ultra-small 8-lead MLFTM package that features a 70% smaller footprint. 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 SY89208V is designed to operate in either ECL/PECL or PECL/LVPECL mode. The SY89208V is internally temperature compensated, thus is 100k EP ECL/PECL compatible--I/O logic levels remain constant over temperature. The SY89208V 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 2, 3 Pin Name DA, DB Type 100k ECL Input 100k ECL Input Negative Power Supply 100k ECL Output Pin Function Single-ended PECL/ECL Inputs: The signal inputs include internal 75k pull-down resistors. Default condition is LOW when left floating. The input signal should be terminated externally. Single-ended PECL/ECL Input: PECL/ECL compatible 2:1 mux select. See Truth Table. Includes internal 75k pull-down resistor. Default condition is LOW when left floating. Negative Power Supply: VEE and Exposed pad must be tied to most negative supply. For PECL/LVPECL connect to ground. Differential PECL/LVPECL Output: 100k ECL/ output defaults to LOW if D inputs left open. See "Output Interface Applications" section for recommendations on terminations. Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors. Not connected.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions for extended periods may affect device reliability. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. Package Thermal Resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB. The device is guaranteed to meet the DC specifications, shown in the table above, after thermal equilibrium has been established. Output loaded with 50 to VCC-2V.

VIHCMR(min) varies 1:1 with VEE, (max) varies 1:1 with VCC. Measured with 750mV input signal, 50% duty cycle. Output swing 400mV. All loading with a 50 to VCC -2.0V. 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. Note 9. 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. Note 10. Random jitter is measured with a K28.7 comma detect character pattern, measured at 1.25Gbps and 2.5Gbps. Note 11. Deterministic jitter is measured at 1.25Gbps and 2.5Gbps, with both K28.5 and 223-1 PRBS pattern. Note 12. Total Jitter definition with an ideal clock input, no more than 1 output edge in 1012 output edges will deviate by more than specified peak-to-peak jitter value.
