IDT VersaClock Low Power Timing Devices

IDT (Integrated Device Technology) introduced the 5P49EE801, 5P49EE802, 5P49EE601, 5P49EE602, and 5P49EE502 VersaClock LP devices. The VersaClock low power devices are available in several package options, including 20-pin and 24-pin QFN. The new timing devices are sampling to qualified customers and range in price from $0.80 to $1.25 for 10,000 units. Evaluation boards are available for qualified customers. The VersaClock low power (LP) devices are programmable clock generators designed to reduce power consumption and optimize board layout in battery-operated consumer applications.

  • Less than 200ps (pico seconds) cycle-cycle jitter (typical)
  • 1.8 – 3.3V LVTTL or LVDS outputs
  • Spread spectrum for EMI reduction
  • Unique video spread capabililty

The five new VersaClock LP timing devices all feature four internal PLLs, each individually programmable and able to generate four unique frequencies, helping optimize the performance of each individual clock output and improving system accuracy. The frequencies can be generated from a clock input, a single TCXO or fundamental mode crystal reference. Using a single reference clock enables designers to simplify design and save board space while still maintaining accuracy.

One of the four internal PLLs supports spread spectrum generation that reduces electromagnetic interference (EMI), which is necessary for meeting FCC and other certification requirements. In addition, the new VersaClock devices can generate frequencies from 5kHz to 120MHz, which enables greater design flexibility for portable consumer applications. The devices are also compatible with many different output types — from single-ended LVCMOS to differential LVDS — to support various types of timing systems with a single device, simplifying design and optimizing board layout.
