Description
Input Clock Frequency, 24MHz to 120MHz.
Digital control input to select multiplication factor and SST modulation
amplitude. Has internal pull-up.
Digital control input to select multiplication factor and SST modulation
amplitude. Has internal pull-up.
Digital control input to select multiplication factor and SST modulation
amplitude. Has internal pull-down.
Ground.
SST Modulated Clock Frequency Output. The frequency before modulation is
synthesized by multiplying the input frequency by 1X, 2X, or 4X, depending on
S(0:3).
Digital control input to select multiplication factor and SST modulation
amplitude. Has internal pull-down.
3.3V Power Supply.
