Input Receiver and Band Gap Control (Register 0x1A)
Table 32.
Address
Bit
Bit Name
Description
0x1A
7
Receiver reset
Input receiver reset control. This is an autoclearing bit.
0 = normal operation (default).
1 = resets the reference input hardware (detectors, dividers, switchover control,
crystal oscillator, and its associated frequency doubler).
[6:2]
Band gap voltage adjust
Controls the band gap voltage setting from minimum (00000) to maximum (11111).
Default is 00000.
The band gap voltage adjust bits are ineffective unless Register 0x1A[0] = 1.
1
Unused
Unused.
0
Enable SPI control of band
gap voltage
Enables functionality of Register 0x1A[6:2].
0 = the device automatically selects receiver band gap voltage (default).
1 = Register 0x1A[6:2] defines the receiver band gap voltage.
XTAL Control (Register 0x1B to Register 0x1E)
Table 33.
Address
Bit
Bit Name
Description
0x1B
7
Disable SPI control of XTAL
tuning capacitance
Disables functionality of Register 0x1B[5:0].
0 = tuning capacitance defined by Register 0x1B[5:0].
1 = the device automatically selects XTAL tuning capacitance (default).
6
Unused
When programming this register write a Logic 0 to this bit.
[5:0]
XTAL tuning capacitor control
Capacitance value coded as inverted binary (0.25 pF per bit); that is, 111111 is 0 pF,
111110 is 0.25 pF, and so on. The default value, 000000, is 15.75 pF. The XTAL tuning
capacitor bits are ineffective unless Register 0x1B[7] = 0.

REFA Frequency Control (Register 0x1F to Register 0x22)
Table 34.
Address
Bit
Bit Name
Description
0x1F
[7:0]
REFA divider (R
A)
Bits[13:6] of the 14-bit REFA divider.
0x20
[7:2]
REFA divider (R
A)
Bits[5:0] of the 14-bit REFA divider (default: R
A = 4096 decimal). The REFA divider bits
are ineffective unless Register 0x20[1] = 1.
1
Enable SPI control of R
A
Enables SPI port control of the REFA divider value (R
A).
0 = the A3 to A0 pins define R
A per Table 14 (default).
1 = the 14-bit value in the REFA divider register defines R
A.
0
Unused
Unused.
0x21
7
Enable SPI control of ×2
A
Enables SPI control of the REFA ×2 frequency multiplier (×2
A) per 0x21[6].
0 = the device automatically selects ×2
A per Table 14 (default).
1 = Register 0x21[6] controls the selection of ×2
A.
6
Select ×2
A
Selects ×2
A. This bit is ineffective unless Register 0x21[7] = 1.
0 = bypass ×2
A (default).
1 = select ×2
A.
5
Enable SPI control of ÷5
A
Enables SPI control of the ÷5
A prescaler per 0x21[4].
0 = the device automatically selects ÷5
A per Table 14 (default).
1 = Register 0x21[4] controls the selection of ÷5
A.
4
Select ÷5
A
Selects ÷5
A. This bit is ineffective unless Register 0x21[5] = 1.
0 = bypass ÷5
A (default)
1 = select ÷5
A.
