Cypress CY24488 Programmable 4-PLL Timing Chip, Suitable for Entertainment Applications

Cypress Semiconductor introduced CY24488, the industry’s first 4-PLL (phase-locked loop) timing device with a 2-wire I2C programming interface. The I2C programming allows programming frequencies on the printed circuit board. It also allows customers to order one part number and use it for multiple products and design iterations, reducing inventory requirements. This chip meets critical timing requirements in digital set-top boxes, DVD recorders, digital TVs and other complex systems requiring synthesis of multiple, unrelated frequencies.

The CY24488 replaces multiple crystals. It provides three independent frequencies and one buffered reference frequency. The programmable output frequencies range from 4.9152 to 148.5 MHz, compatible with most digital entertainment devices. The device has an integrated analog voltage controlled crystal oscillator (VCXO) with a minimum pull range of ± 120 ppm for maximum frequency resolution and better frequency tracking.

Wayne Gill, managing director of Cypress’s General-Purpose Clock Business Unit:

As our recent design win with Hitachi shows, we offer superior timing solutions for the digital entertainment market…

…The addition of I2C programming gives customers another reason to choose Cypress for these applications.

Price and Availability
The CY24488 comes in a space-efficient 16-lead TSSOP package. It is priced starting at $1.95 in 1,000-unit quantities.
