DESCRIPTION

The SY89829U is a High Performance dual 1:10 or

single 1:20 LVPECL Clock Driver. The part is designed for

use in low voltage (2.5V/3.3V) applications which require a

large number of outputs to drive precisely aligned, ultra low

skew signals to their destination. The input is multiplexed

from either LVDS or LVPECL by the CLK_SEL pin. The

LVDS inputs include a 100Ω internal termination across

the input pair, thus eliminating any need for external

termination. The 2:1 input mux makes this device an ideal

choice for redundant clock applications that need to switch

between two reference clocks. The output enable (OE) is

synchronous so that the outputs will only be enabled/

disabled when they are already in the LOW state. This

eliminates any chance of generating a runt clock pulse

when the device is enabled/disabled as can happen with an

asynchronous control.

The SY89829U features low pin-to-pin skew (50ps max.)

and low part-to-part skew (200ps max.)—performance

previously unachievable in a standard product having such

a high number of outputs. The SY89829U is available in a

single space saving package which provides a lower overall

cost solution. In addition, a single chip solution improves

timing budgets by eliminating the multiple device solution

with their corresponding large part-to-part skew.

APPLICATIONS

Parallel processor-based systems
