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 company said.
The new timing devices offer reduction in power consumption to meet the increasing demand for power efficiency in consumer electronic devices.
The company added that the VersaClock LP devices help extend the battery life for portable electronics by reducing the power requirement from 30-40mW to 4-8mW for a single clock output. The VersaClock LP systems also reduce the power usage during power down (20uW) and sleep mode with 32kHz clock active (200uW).
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 frequencies.
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.
The new VersaClock devices can generate frequencies from 5kHz to 120MHz, which enables 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, the company claimed.
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.
