VersaClock Programmable Clock Generator

IDT VersaClock® products are programmable clock generator devices that save cost, reduce board space and greatly increase versatility in consumer, data communications, telecommunications and networking applications. These devices are often referred to as programmable clock generators, or programmable PLL clock generators.

VersaClock programmable clock generators allow designers to save board space and cost by replacing crystals, oscillators (including programmable oscillators), and buffers with a single timing device. IDT's VersaClock product portfolio contains parts with up to four internal PLLs, each individually programmable, allowing for up to seven unique frequencies. When used with a TCXO (temperature compensated crystal oscillator) input, all outputs will track the source accuracy, allowing consolidation of multiple TCXOs.

Various subsets of the VersaClock family are targeted for different applications, including VersaClock 5, VersaClock III, VersaClock LP. For low-power, high-performance applications, VersaClock 5 provides 0.7ps phase jitter, and the ability to store up to four different frequency configurations in a single device. With RMS phase jitter less than 0.7 picoseconds over the full 12 kHz to 20 MHz integration range, VersaClock 5 meets the stringent jitter requirements of PCI Express Gen 1/2/3, USB 3.0, and 1G/10G Ethernet. The high-performance clock generator operates at less than 100 mW core power (50 percent lower than competing devices), helping to ease system thermal constraints, reduce operating power expenses. For consumer systems, VersaClock III and LP (low power) provide flexibility with an internal EEPROM that makes it simple to reprogram frequencies for changing system requirements through the use of the I2C interface.

The IDT VersaClock Programmable product line provides a competitive solution to your product needs and time-to-market requirements. VersaClock products from IDT provide an almost universal solution for a variety of high performance clock applications.
