High-performance crystal oscillators offer best-in-class jitter performance

Latest from Integrated Device Technology (IDT) is news of the expansion of its comprehensive timing portfolio with the introduction of two new families of crystal oscillators. The IDT XU and XL families offer unparalleled features and flexibility at an industry-leading price / performance ratio. The high-performance, low-phase jitter crystal oscillators are customizable for frequencies from 16kHz to 1.5GHz, with 300 fs RMS phase jitter, and are available in HCMOS, LVPECL, LVDS, and HCSL outputs. To shorten time to market, IDT is offering fast delivery of its custom-frequency oscillators. Engineers used to waiting up to months from other vendors can expect to receive the new IDT crystal oscillators in two weeks or less, says the company. “The XU and XL crystal oscillators are IDT’s response to the increasingly stringent jitter requirements resulting from higher data throughput in serial IO technologies,” said Dave Shepard, vice president and general manager Timing and RF Division, IDT. “Our new oscillators offer designers a reliable and economical solution to address the growing challenges of frequency control.” The devices feature a typical jitter value of 300fs RMS with a maximum value of 400fs, integrated over 12kHz to 20MHz. They are particularly suitable for such applications as networking, communications, data I/O, storage and servers. The XU and XL families deliver varying throughput speeds to match the requirements of individual designs. The XU family is offered in LVPECL, LVDS, HCSL and HCMOS versions, with operating voltages of 3.3V, 2.5V or 1.8V. The devices offer frequency stabilities as low as +/-20 ppm with a temperature range as wide as -40C to 85C in industry standard packages of 7mm x 5 mm and 5mm x 3.2mm.
