MEMS based PLL clock generators from IDT

Integrated Device Technology has introduced low-power, multi-output PLL clock generators using IDT's patented Piezoelectric MEMS (pMEMS) technology.

The new devices can work without external crystals and oscillators. The IDT5V8001x and IDT5V8002x families are high-performance single- and dual-output ±50 ppm timing devices incorporating IDT's CrystalFree pMEMS resonators. This family of devices provides two independent single-ended output frequencies at up to 200 MHz. IDT claims the multi-output devices consume up to 75 percent less power than competitive two-output spread spectrum-enabled MEMS timing solutions, making them well-suited for battery-powered portable devices or cooling-hungry enterprise datacenters. These pMEMS-based clock generators are available in standard 3x3 mm QFN packaging and operate across the full industrial temperature range.

"Our new CrystalFree pMEMS-based clock generators redefine the standard for high-performance, easy-to-use timing solutions and grow IDT's portfolio of products and technologies that address the $4B frequency control market," said Fred Zust, vice president and general manager of the Timing and Synchronization Division at IDT. "By eliminating the crystal and integrating the PLLs, we've taken the ambiguity out of building a timing solution, and consolidated the outputs into a single device with a smaller footprint. Our growing pMEMS portfolio further strengthens our leadership position in timing and delivers the highest level of innovation to advance our customers' next-generation designs."

Some of the new clock generator devices feature spread spectrum capability that can be toggled using hardware select pins, allowing the designer to reduce electro-magnetic interference (EMI) in-system during compliance testing, rather than redesigning the whole board. In addition, the devices operate with only 75 ps of short-term cycle-cycle jitter, meeting the demands of high-performance PC and consumer markets.

Pricing and Availability: The IDT IDT5V8001x and IDT5V8002x families are currently sampling to select customers.
