IDT intros industry-first programmable low power timing devices optimized for portable consumer apps

SAN JOSE, USA: IDT (Integrated Device Technology Inc.) has announced the newest members of its IDT VersaClock family of timing devices.

The VersaClock low power (LP) devices are programmable clock generators specifically designed to reduce power consumption and optimize board layout in battery-operated consumer applications including smart mobile handsets, personal navigation devices, MP3 players, camcorders, and other handheld applications

The new timing devices offer a significant reduction in power consumption to meet the increasing demand for power efficiency in consumer electronic devices. The VersaClock LP devices help extend the battery life for today’s portable electronics by reducing the power requirement from 30-40mW to 4-8mW for a single clock output.

The VersaClock LP solutions also significantly reduce the power usage during power down (20uW) and sleep mode with 32kHz clock active (200uW). These are new low power benchmarks for the industry.

The five new VersaClock LP devices (5P49EE801, 5P49EE802, 5P49EE601, 5P49EE602 and 5P49EE502) 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. To give designers great flexibility, the frequencies are may be generated from a clock input, a single TCXO or fundamental mode crystal reference. Using a single reference clock allows designers to simplify design and save board space while still maintaining accuracy.

One of the four internal PLLs supports spread spectrum generation which reduces electromagnetic interference (EMI), which is necessary for meeting FCC and other certification requirements. Moreover, the new VersaClock devices can generate frequencies from 5kHz to 120MHz, which enables greater design flexibility for portable consumer applications.

In addition, 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.

The VersaClock low power devices are available in several package options, including 20-pin and 24-pin QFN. The new 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.
