2Gbps, DIFFERENTIAL 4:1 LVDS MULTIPLEXER WITH INTERNAL INPUT TERMINATION Precision Edge® SY89544U ® Precision Edge SY89544U FEATURES Selects among four differential inputs Precision Edge® Guaranteed AC performance over temp and voltage: • DC-to > 3.
2Gbps data rate throughput DESCRIPTION • < 600ps In-to-Out tpd The SY89544U is a fast, low-jitter, 4:1 differential MUX • < 150ps tr/tf with an LVDS (350mV) compatible output with guaranteed Ultra low-jitter design: data rate throughput of 3.
2Gbps over temperature and • < 1psRMS random jitter voltage.
• < 10psPP deterministic jitter The SY89544U differential inputs include a unique, 3-pin • < 10psPP total jitter (clock) internal termination that allows access to the termination • < 0.
7psRMS crosstalk-induced jitter network through a VT pin.
This feature allows the device to Unique input isolation design minimizes crosstalk easily interface to different logic standards, both AC- and Internal input termination DC-coupled without external resistor-bias and termination Unique input termination and VT pin accepts DCnetworks.
The result is a clean, stub-free, low-jitter interface Coupled and AC-Coupled inputs (LVDS, LVPECL, solution.
CML) The SY89544U operates from a single 2.
5V supply and 350mV LVDS output swing is guaranteed over the full industrial temperature range (–40°C to +85°C).
For applications that require a 3.
3V supply, CMOS/TTL compatible MUX select consider the SY89545L.
For applications that require two Power supply 2.
5V ±5% differential outputs, consider the SY89546U or SY89547L.
–40°C to +85°C temperature range The SY89544U is part of Micrel’s Precision Edge® product Available in 32-pin (5mm × 5mm) MLF® package www.
