It is functionally equivalent to the SY100EP58V but in an ultra-small 8-lead MLF™ 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 –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 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 c...
