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 5 product portfolio contains parts with up to four programmable universal output pairs that are capable of selecting between differential (LVPECL, LVDS, and HCSL) and LVCMOS outputs. With the help of FOD (fractional output divider) technology, VersaClock 5 and VersaClock 6 are capable of accurately generating up to four independent output frequencies.

Various subsets of the VersaClock family are targeted for different applications, including VersaClock 5, VersaClock 6, VersaClock 3S, 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.

The VersaClock 6 programmable clock generator family delivers flexible, low-power timing for demanding high-performance applications. With RMS phase jitter of less than 500 femtoseconds (fsec), the VersaClock 6 products deliver the best performance to date for IDT’s award-winning VersaClock family, offering an exceptional combination of jitter performance, flexibility, and low operating power.With RMS phase jitter less than 500 fsec over the full 12 kHz to 20 MHz integration range, the new devices meet the stringent jitter and phase noise requirements of such technologies as10G Ethernet, PCI Express Gen 1/2/3, stringent PHY reference clocks and the newest generations of high-end FPGAs — all while operating at about half the core power of competing devices. The devices’ core current consumption of 30 mA eases system thermal constraints and reduces operating power expenses. In addition, the VersaClock 6 devices are footprint compatible with their VersaClock 5 counterparts, enabling performance scalability with minimal design changes.

The VersaClock 3S devices deliver innovative power-saving features while saving board space by eliminating the need for multiple discrete timing components. Delivering low power and low jitter scalability, the VersaClock 3S devices meet requirements for widely used standards including PCI Express® Gen 1/2/3 and are ideal for consumer, industrial, computing and automotive applications.

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.
