onsemi P2814B
The P28XX devices are versatile spread spectrum frequency modulators designed specifically for a wide range of input clock frequencies from 10MHz to 40MHz. The P28XX can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P28XX-A and the P28XX-B offer various combinations of spread options and percentage deviations.FEATURES
● FCC approved method of EMI attenuation● Provides up to 15dB EMI reduction
● Generates a 1x, 2x and 4x low EMI spread spectrum clock of the input frequency o 1x: P2811A/B o 2x: P2812A/B o 4x: P2814A/B
● Optimized for input frequency range from 10MHz to 40MHz
● Internal loop filter minimizes external components and board space
● Selectable spread options: o Down Spread and Center Spread
● 8 frequency deviation selections: o ±0.625% to -3.5%
● Low inherent Cycle-to-Cycle Jitter
● 3.3V Operating Voltage
● CMOS/TTL compatible inputs and outputs.
● Pin-out compatible with Cypress CY25811, CY25812 and CY25814
● Available in 8-pin SOIC Package Product
DESCRIPTION
Refer to Input/output Frequency Range Selection Table. Refer to Frequency Deviation and Spread Selection Table. These combinations include Down and Center Spread, and percentage deviation range from ±0.625% to -3.5%. The P28XX reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of downstream clock and data dependent signals.
