Alliance Semiconductor P2811/12/14 Data Sheet1

Update: 28 September, 2023

The document provides information about the features and characteristics of Alliance Semiconductor P28xx series low-power EMI reduction integrated circuits. These ICs utilize an FCC approved method of EMI attenuation and can provide up to 15 dB of EMI reduction. They generate 1X, 2X, and 4X low EMI spread spectrum clocks based on the input frequency. The P28xx series is optimized for input frequencies ranging from 10 to 40 MHz and includes an internal loop filter to minimize external components and board space. It supports selectable spread options including Down Spread and Center Spread, with low inherent cycle-to-cycle jitter. The ICs operate at 3.3V and are CMOS/TTL compatible. They have a pinout compatible with Cypress CY25811, CY25812, and CY25814. The P28xx series is available for industrial temperature range and comes in 8-pin SOIC and TSSOP packages.
