Quad-PLL has time for digital
entertainment
Cypress Semiconductor has introduced the industry's first quad-PLL (phase-locked loop) timing device with a two-wire I2C programming interface.
Cypress Semiconductor has introduced the industry's first quad-PLL (phase-locked loop) timing device with a two-wire I2C programming interface The I2C programming allows manufacturers to reduce time to market by programming frequencies on the printed circuit board instead of having to order factory-programmed parts or use an additional manufacturing step

Serial interface engine provides USB 2.0 for MCUs
Cypress Semiconductor has expanded its USB 2.0 product line with the introduction of the EZ-USB SX2 intelligent serial interface engine (SIE).
It also allows customers to order one part number and use it for multiple products and design iterations, reducing inventory requirements.
The new CY24488 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, reducing BOM (bill of materials) cost.
It provides three independent frequencies and one buffered reference frequency.
The programmable output frequencies range from 4.9152 to 148.5MHz, compatible with most digital entertainment devices.
The device has an integrated analogue voltage controlled crystal oscillator (VCXO) with a minimum pull range of +/-120ppm for maximum frequency resolution and better frequency tracking.
It also includes programmable output drive strength for EMI control and a 2.5V option to interface with lower voltage ICs without extra circuitry.
"As our recent design win with Hitachi shows, we offer superior timing solutions for the digital entertainment market", said Wayne Gill, Managing Director of Cypress's General-Purpose Clock Business Unit.
"The addition of I2C programming gives customers another reason to choose Cypress for these applications".
The CY24488 comes in a space-efficient 16-lead TSSOP package.
It is priced starting at US $1.95 in 1000-unit quantities.
