IDT announces 'Industry first' programmable low power timing devices

The mixed signal semiconductor specialist says that the VersaClock low power devices are programmable clock generators specifically designed to reduce power consumption and optimise board layout in battery-operated consumer applications. These include smart mobile handsets, personal navigation devices, MP3 players, camcorders, and other handheld applications According to IDT, the new timing devices offer a 'significant reduction' in power consumption to meet the increasing demand for power efficiency in consumer electronic devices. The devices have been designed to extend battery life by reducing the power requirement from 30 to 40mW to 4 to 8mW for a single clock output. The devices are also said to reduce the power usage during power down (20µW) and sleep mode with 32kHz clock active (200µW). The five new VersaClock low power devices (5P49EE801, 5P49EE802, 5P49EE601, 5P49EE602 and 5P49EE502) incorporate four internal PLLs, each individually programmable and able to generate four unique frequencies. These can be generated from a clock input, a single tcxo or fundamental mode crystal reference. One of the four internal PLLs supports spread spectrum generation which reduces emi, while the devices can generate frequencies from 5kHz to 120MHz, which enables design flexibility for portable consumer applications. The VersaClock low power devices are available in several package options, including 20 and 24pin QFN. The new devices are sampling to qualified customers, evaluation boards are also available for qualified customers.
