New Cypress 4-PLL Timing Chip Is First With 2-Wire I2C Interface, Allowing On-Board Programming For Fast Time-to-Market And Reduced Inventory.Delivers High Performance Clocking for Digital Entertainment Devices and Other Applications Requiring Multiple Frequencies SAN JOSE, Calif. -- Cypress Semiconductor Corp. (NYSE NYSE See: New York Stock Exchange :CY) today introduced the industry's first 4-PLL (phase-locked loop) timing device with a 2-wire I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller 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. 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 The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. ) cost. It provides three independent frequencies and one buffered reference frequency. The programmable output frequencies range from 4.9152 to 148.5 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , compatible with most digital entertainment devices. The device has an integrated analog voltage controlled crystal oscillator (VCXO VCXO Voltage Controlled Crystal Oscillator ) with a minimum pull range of 120 ppm for maximum frequency resolution and better frequency tracking. It also includes programmable output drive strength for EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. control and a 2.5-V 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." Price and Availability The CY24488 comes in a space-efficient 16-lead TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package package. It is priced starting at $1.95 in 1,000-unit quantities. A high-resolution photo of the new device can be downloaded at www.cypress.com/24488-photo.
