New Devices Combine Two Independent Clock Outputs with Advanced PLL Technology; Delivers Extremely Low Jitter
SANTA CLARA, Calif.--(BUSINESS WIRE)--June 16, 2003-- IDT(TM) (Integrated Device Technology, Inc.; Nasdaq: IDTI), a leading communications IC company, today marked its entry into the high-precision clock generation market with the introduction of its new precision clock generation devices with patent-pending, phased-locked loop (PLL) technology. The 5T940 clock generators achieve ultra-low jitter generation of less than 0.5 psRMS, making them ideal for Gigabit Ethernet and SONET applications up to OC-192. The new devices provide two independent clock outputs, with three modes of operation, making them more flexible than alternative solutions. The 5T940 precision clock generators offer a host of other value-added features, including a "jitter-cleaning" capability, selectable-loop bandwidth, a wide range of multiply options and hitless auto switchover capability for robust clock redundancy.
"The 5T940 precision clock generators replace long lead time fixed frequency oscillators and surface acoustic wave filters with much more flexible, value-rich devices," stated Kevin Walsh, director of strategic marketing for the IDT timing and logic divisions. "Leveraging our expertise in timing technology, we are able to bring to market a family of devices that, unlike competing products, delivers extremely low jitter while offering the flexibility that enables designers of Gigabit Ethernet and SONET applications to easily satisfy their clock-source requirements. Our new 5T940 precision clock generators are a proof-point of our ability to provide innovative clock generation products for leading-edge communications applications."
The IDT 5T940 clock generators include a clock regeneration feature that is able to attenuate jitter from recovered clocks from line transceiver devices. To support robust clock redundancy for high-performance applications, the clock generators provide a hitless switchover capability, with period deviation as low as 0.005 percent per cycle. The devices also support multiplier ratios of 2, 4, 8, 16 and 32, and feature selectable-loop bandwidth, which allow the 5T940 clock generators to be tuned for specific applications. The jitter cleaning capability enables the device to accept an input clock with relatively high jitter, and then reduce the jitter to meet the requirements of a line transmission device such as a SONET or Gigabit Ethernet transceiver.
The two independent clock outputs support three modes of operation: 155.5 to 166.6 MHz, 622 to 666.5 MHz output; 155.5 to 166.6 MHz output, regenerated version of input clock; and 622 to 666.5 MHz output, regenerated version of input clock.
In addition, the 5T940 clock generators can be used in conjunction with the IDT WAN PLL devices to provide Stratum-3 compliant clock generation that also meets SONET/SDH jitter requirements.
