I1821G-08TT Product details

Product Description
The P18xx is a versatile spread spectrum frequency modulator designed specifically for a wide range of input clock frequencies from 10 to 160 MHz (see Input Frequency and Modulation Rate Selections). The P18xx can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P18xx-A to P18xx-H offer various combinations of spread options and percentage deviations (see Spread Deviation Selections). These combinations include Down Spread, Center Spread and percentage deviation range from ±0.625% to -3.50%.

Features
• FCC approved method of EMI attenuation
• Provides up to 15 dB EMI reduction
• Generates a low EMI spread spectrum clock and a non-spread reference clock of the input frequency
• Optimized for frequency range from 10 MHz to 160 MHz
    P1818: 10 to 20 MHz
    P1819: 20 to 40 MHz
    P1820: 40 to 80 MHz
    P1821: 10 to 40 MHz
    P1822: 80 to 160 MHz
• Internal loop filter minimizes external components and board space
• Selectable spread options: Down Spread and Center Spread
• Low inherent cycle-to-cycle jitter
• Eight spread % selections: +/-0.625% to –3.5%
• 3.3V operating voltage
• CMOS/TTL compatible inputs and outputs
• Low power CMOS design
• Supports notebook VGA and other LCD timing controller applications
• Power down function for mobile application
• Products are available for industrial temperature range.
• Available in 8-pin SOIC and TSSOP
