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
■ Communications
