The P28XX devices are versatile spread spectrum frequency modulators designed specifically for a wide range of input clock frequencies from 10MHz to 40MHz. Refer to Input/output Frequency Range Selection Table. 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.
• 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.
