XRT8010
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.
