简  介:ABE0101/02/04/06 Low EMI Spread Spectrum Multiplier Clock FEATURES Spread Spectrum Clock Generator with selectable multiplier from 1x to 6x outputs. Output frequency ranges: 10MHz to 180MHz. Accepts input from crystal or reference clock. Selectable Center, Down or Asymmetric Spread Modulation. Selectable Modulation rate. TTL/CMOS compatible outputs. 3.3V Operating Voltage. Low short term jitter. Available in 8-Pin 150mil SOIC. PIN CONFIGURATION XIN/FIN XOUT/SD*^ SC0^ SC1^ 1 8 VDD SC2^ FOUT GND ABE010x 2 3 4 7 6 5 XIN/FIN = 10 ~ 30 MHz Note: ^: Internal pull-up resistor (120k for SD, 30 k for SC0-SC2). *: The value of SD is latched upon power-up. The internal pull-up resistor results in a default high value when no pull-down resistor is connected to this pin (recommended external pull-down resistor of 27 k ). DESCRIPTION The ABE0101/02/04/06 are Spread Spectrum Clock Generators designed for the purpose of reducing EMI in high-speed digital systems. Any output frequency from 10 to 180MHz can be selected by programming 6 multiplier modes. The device is designed to operate from a crystal or reference clock input and provides 1x to 6x modulated clock outputs.
