The SY89831U is a high-speed, 2GHz differential LVPECL 1:4 fanout buffer optimized for ultra-low skew applications. Within-device skew is guaranteed to be less than 20ps (5ps typ.) over supply voltage and temperature. The differential input buffer has a unique internal termination design that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards. A VREF-AC reference output is included for AC-coupled applications.The SY89831U is a part of Micrel's high-speed clock synchronization family. For applications that require a different I/O combination, consult Micrel’s website and choose from a comprehensive product line of high-speed, low-skew fanout buffers, translators, and clock generators.
Additional Features
Guaranteed AC performance over temperature and voltage:
DC-to-2.5GHz throughput (typical)
350ps propagation delay (IN-to-Q) (typical)
5ps within-device skew (typical)
150ps rise/fall time (typical)
Ultra-low jitter design:
62fsRMS phase jitter (typical)
Unique patent-pending input termination and VT pin accepts DC- and AC-coupled differential inputs
800mV, 100K LVPECL typical output swing
Power supply 2.5V ±5% or 3.3V ±10%
Industrial temperature range: -40°C to +85°C
Available in 16-pin (3mm x 3mm) MLF® package
