Analog-to-digital converter (ADC) electrical characteristics
The device provides a 10-bit successive approximation register (SAR) analog-to-digital converter.
4 Self-clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls outside
the fLOR window.
5 f
VCO self clock range is 20–150 MHz. fSCM represents fSYS after PLL output divider (ERFD) of 2 through 16 in
enhanced mode.
6 This value is determined by the crystal manufacturer and board design.
7 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum
fSYS. Measurements are made with the device powered by filtered supplies and clocked by a stable external clock
signal. Noise injected into the PLL circuitry via VDDPLL and VSSPLL and variation in crystal oscillator frequency
increase the CJITTER percentage for a given interval.
8 Proper PC board layout procedures must be followed to achieve specifications.
9 Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of C
JITTER and
either fCS or fDS (depending on whether center spread or down spread modulation is enabled).
10 Short term jitter is measured on the clock rising edge at cycle n and cycle n+4.
11 This value is determined by the crystal manufacturer and board design. For 4 MHz to 20 MHz crystals specified for
this PLL, load capacitors should not exceed these limits.
12 This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits
in the synthesizer control register (SYNCR).
13 This value is true when operating at frequencies above 60 MHz, otherwise f
CS is 2% (above 64 MHz).
14 Modulation depth will be attenuated from depth setting when operating at modulation frequencies above 50 kHz.
