CCB<15:8>: Command Code bits
The command code bits ( 11001100b ) are serially sent to the microcontroller to identify the bits to be
written in the PLLCREG.
Unimplemented: Write as ‘ 0 ’
CBTC<1:0>: Clock Buffer Time Control bits
These bits control the rise and fall time for the clock buffer which is dependant on the output clock
frequency from the BCSREG.
11 = 5 MHz - 10 MHz
10 = 3.3 MHz
01 = 2.5 MHz or less
00 = 2.5 MHz or less
Reserved: Masked to ‘ 1 ’
PDDS: Phase Detector Delay Switch bit
1 = Enables the phase detector delay function
0 = Disables the phase detector delay function
PLLDD: PLL Dithering Disable bit
1 = Disables PLL dithering
0 = Enables PLL dithering
Reserved: Write as ‘ 1 ’
PLLBWB: PLL Bandwidth bit
Enabling the bit configures higher data rates, faster settling and reduced phase noise; thus, resulting
in a better RF performance.
1 = -102 dBc/Hz, > 90 kbps (max 256 kbps)
0 = -107 dBc/Hz, < 90 kbps (max 86.2 kbps)
