XRT8010IL-F

XRT8010 312MHZ CLOCK & CRYSTAL MULTIPLIER WITH LVDS OUTPUTS NOVEMBER 2003 REV. 1.0.2 DESCRIPTION ■ FEATURES 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. • 156 or 320 MHz Operating Range • Low Output Jitter: ■ 0.0009 UIRMS typical @ 155.52 MHz, per Telcordia GR-253-CORE for OC-3. • On Chip Crystal Oscillator Circuit ■ Optimized for 15 to 40 MHz crystals ■ Uses parallel fundamental mode • Selectable 8x or 16x multiplier • Selectable ÷1 or ÷2 LVDS output APPLICATIONS • LVDS output meets TIA/EIA 644A Specification • Gigabit Ethernet • SONET/SDH • SPI-4 Phase 2 • 8x or 16x Clock Multiplier for ■ Telecommunications Sytems (2001) • 3.3V Low power CMOS:
