Perform tuning on LC portion of the ADC (cleared when done).
Perform tuning on RC portion of the ADC (cleared when done).
Coarse capacitance setting of LC tank (LSB is 25 pF, differential).
Enable read from SPI port.
Three-state DOUTB.
Description
Synthesized frequency divisor (8 LSBs of a 13-bit word).
Default yields 300 kHz from 18 MHz; Minimum = 3,
Maximum = 8191.
Enable fast acquire.
Invert charge pump (0 = source current to increase VCO
frequency).
Charge pump current in normal operation.
I
Manual control of CLK charge pump (0 = Off, 1 = Up, 2 = Down,
and 3 = Normal).
CK fast acquire time unit (6 LSBs of a 14-bit word).
CK fast acquire time unit (8 LSBs of a 14-bit word).
SSI Control Register A. See Table 8. Default is FS and CLKOUT
three-stated.
SSI Control Register B. See Table 8 (16-Bit Data, maximum drive
strength).
Output rate divisor. f
Fine capacitance setting of LC tank (LSB is 0.4 pF, differential).
Capacitance setting for RC resonator (64 LSB of fixed
capacitance).
