DESCRIPTION

The SY89828L is a precision fanout buffer with 20 differential LVDS (Low Voltage Differential Swing) output pairs. The part is designed for use in low voltage 3.3V applications that require a large number of outputs to drive precisely aligned, ultra low-skew signals to their destination.

FEATURES

■ High-performance dual 1:10, 1GHz LVDS fanout buffer/translator

■ Two banks of 10 differential LVDS outputs

■ Guaranteed AC parameters over temperature and voltage:

• > 1GHz fMAX

• < 50ps within device skew

• < 400ps tr, tf time

■ Each bank includes a 2:1 input mux

■ 2:1 mux input accepts LVDS and LVPECL

■ Low jitter performance

• < 1psRMS cycle-to-cycle jitter

• < 1psPP total jitter

■ 3.3V supply voltage

■ Output enable function

■ LVDS input includes internal 100Ω termination

■ Available in a 64-Pin EPAD-TQFP

APPLICATIONS

■ Enterprise networking

■ High-end servers
