FS6233-01 Datasheet PDF - AMI Semiconductor

Features
• Generates all clocks required for single-processor platforms, including:
    ♦ Two differential current-mode Host clock pairs
    ♦ Three 66.67MHz 3.3V CK66 clock outputs
    ♦ Ten 33.3MHz 3.3V PCI clock outputs
    ♦ Two 3.3V Memory Reference clock outputs
    ♦ Two 48MHz 3.3V CK48 clock outputs
    ♦ Two buffered copies of the crystal reference
• Control of current-mode Host clocks via IREF current programming pin and ISEL_0:1 current multiplier pins
• Host clock frequency selection via the SEL_A, SEL_B, and SEL133/100# pins
• Active-low PWR_DWN# signal allows one complete clock cycle on each clock outputs and then shuts down the crystal oscillator, PLLs, and outputs
• Spread-spectrum modulation (-0.5% at 31.5kHz) of SSCG PLL clocks, enabled via SS_EN# input
• Supports test mode and tristate output control to facilitate board testing
• Available in a 48-pin SSOP and TSSOP
