San Jose, Calif.IDT (Integrated Device Technology Inc.) has rolled out the latest in its VersaClock series: low-power programmable clock generators designed to reduce power consumption and optimize board layout in battery-operated consumer applications.
The VersaClock low power (LP) timing devices offer a sharp reduction in power consumption to meet the increasing demand for power efficiency in consumer electronic devices, including smart mobile handsets, personal navigation devices, MP3 players, camcorders, and other handhelds.
To help extend battery life in portable electronics, the VersaClock LP devices reduce the power requirement from 30-40mW to 4-8mW for a single clock output. They also significantly reduce the power usage during power down (20µW) and sleep mode with 32kHz clock active (200µW).
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). 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 LVDSto 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.
Pricing: From $0.80 to $1.25 for 10,000 units.
Availability: Sampling to qualified customers.
