With the launch of these PLL clock generators, Integrated Device Technology has expanded its timing portfolio by merging the capabilities of two crystal oscillators, ensuring that external oscillators and crystals are no longer needed. This allows customers to facilitate their designs and decrease the bill-of-materials in a variety of applications such as mobile, cloud computing and industrial.
The IDT5V8001x and IDT5V8002x portfolios are high-performance timing devices integrating CrystalFree pMEMS resonators of Integrated Device Technology. Together with the company’s ultra-low-power PLL technology, this portfolio of devices offers two independent single-ended output frequencies of the order of up to 200 MHz, thus enabling system designers to facilitate trace routing, save board space, decrease component count and reduce testing costs.
Power consumption of these multi-output devices is up to 75% lesser than that of competitive spread spectrum-enabled two-output MEMS timing devices. Thus these pMEMS-based devices are ideal for cooling-hungry enterprise datacenters or battery-powered portable devices. They operate over the complete industrial temperature range and offer high reliability in typical 3x3 mm QFN packaging.
Some of these clock generators have spread spectrum functionality that can be connected utilizing hardware select pins, eliminating the redesigning of the entire board by enabling designers to decrease electro-magnetic interference in-system in compliance testing. Moreover, the devices operate with a temporary cycle-cycle jitter of mere 75 ps, thus fulfilling the needs of superior performance consumer and PC markets.
