Output Details
Output Compatability
CMOS
Drive Capability
15pF max
Modulation Ratios:
Centre Spread ±0.25%, ±0.5%, ±0.75%, ±1%, ±1.5%, ±2%
Down Spread -0.5%, -1%, -1.5, -2%, -3%, -4%
Output Control
Tri-state Operation:
Logic '1' (>70%Vs) to pad 1 enables oscillator output
Logic '0' (<30%Vs) to pad 1 disable oscillator output, the
oscillator goes into a high impedance state
No connection to pad 1 enables oscillator output
Spread Spectrum Operation:
Logic '1' to pad 2 (>70% Vs) spread spectrum is off
Logic '0' to pad 2 (<30% Vs) spread spectrum is on
No connection to pad 2 spread spectrum is on
Noise Parameters
Cycle to Cycle Jitter (SS on):
8MHz to <133MHz: 400ps max pk-pk
133MHz to 170MHz: 250ps max pk-pk
