3V/5V 3GHz PECL/ECL 2:1 MULTIPLEXER Precision Edge® Precision ESdYg89e2®08V SY89208V FEATURES s 2:1 PECL/ECL multiplexer s Guaranteed AC-performance over temperature/ voltage • >3GHz fMAX (toggle) • <200ps rise/fall time • <420ps propagation delay (D-to-Q) s Low jitter performance • <1psRMS random jitter • <15psPP deterministic jitter • <10psPP total jitter (clock) s Flexible supply voltage: 3V to 5.
5V 100k ECL/PECL compatible output s Wide operating temperature range: –40°C to +85°C s Available in ultra-small 8-pin MLF™ (2mm x 2mm) package APPLICATIONS s SONET s Gig Ethernet s Fibre Channel s Transponders DESCRIPTION Precision Edge® 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 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 compatible—I/O logic levels remain constant over temperature.
The SY89208V 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.
