312MHZ CLOCK & CRYSTAL MULTIPLIER WITH LVDS OUTPUTS

NOVEMBER 2003

REV. 1.0.2

DESCRIPTION

The XRT8010 is a monolithic analog phase locked

loop that provides a high frequency LVDS clock

output, using a low frequency crystal or reference

clock. It is designed for SONET/SDH and other low

jitter applications.The high performance of the IC

provides a very low jitter LVDS clock output up to 320

MHz, while operating at 3.3 volts. The XRT8010 has

a selectable 8x or 16x internal multiplier for an

external crystal or signal source. The Output Enable

pin provides a true disconnect for the LVDS output.

The very compact (4 x 4 mm) low inductance

package is ideal for high frequency operation.
