1/30/2003 - Exar Corporation (Nasdaq: EXAR), a leading provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure added to its product offerings a new low power, high-speed clock multiplier for frequency synchronization. Providing the same proven low jitter and high performance as the previously announced XRT8020 (650 MHz), the XRT8010 gives OEMs a cost-effective solution for specialized lower frequency applications (up to 350MHz). The device offers a Low Voltage Differential Signaling (LVDS) interface, and improved accumulated jitter (6 ps rms at 311 MHz) -- all at very low power dissipation levels (less than 80 mW typical at 3.3V). The XRT8010 is ideal for manufacturers of communications equipment, and hybrid crystal oscillator manufacturers for telecommunications applications at Gigabit Ethernet and SONET/SDH speeds.
"The XRT8010 gives customers a new option for their designs, and adds to Exar's growing telecommunications timing product family," said Dr. Roubik Gregorian, executive VP and general manager Communications Division, CTO. "This clock multiplier chip can be designed into a wide range of telecom systems requiring high-speed clocks. The device offers the combination of advanced features and performance, in a small footprint, and very low power consumption."
Supporting higher data rates is increasingly in demand for various telecommunications platforms. To overcome the limited clock rates available from crystal manufacturers, Exar's XRT8010 achieves clock signals up to 350 MHz by multiplying the frequency of a standard low cost crystal oscillator (in the range of 20 to 40 MHz), or an external clock source. The device utilizes an analog phase locked loop to multiply by a factor of 6 or 8 the frequency of the input reference clock. The device provides an LVDS output that meets TIA/EIA 644A (2001) specifications.
Price, Package and Availability
The XRT8010 operates at 3.3V over the industrial temperature range and is offered in a very small 16-lead QLP package. In 1,000 piece quantities, the XRT8010 is $4.20. Samples and an evaluation kit are currently available.
