Table 5. CX74038 Register Descriptions (2 of 2)
Symbol
Function
Description
Register Word Address 10
Address bits [1:0]
10
SP2
IF synthesizer phase detector output polarity
[2]
Bit [2] sets the IF synthesizer phase detector output:
0 Sets phase detector output for negative VCO gain
1 Sets phase detector output for positive VCO gain
EN
Enable mode [4:3]
Bits [4:3] enable the RF and/or IF synthesizers:
bit 4
bit 3
0
Enables both RF SX and IF SX
0
1
Enables only RF SX
1
0
Enables only IF SX
1
Sets power-down mode for both RF/IF SX
N2
IF synthesizer main divider [21:5]
Bits [21:5] set the IF synthesizer 17-bit main divider ratio
Register Word Address 11
Address bits [1:0]
11
FN
RF synthesizer fractional-N division [9:2]
Bits [9:2] set the RF synthesizer’s fractional-N program up to 256 modulo
N1
RF synthesizer main divider [21:10]
Bits [21:10] set the RF synthesizer’s 12-bit main divider ratio with a 16/17 prescaler, or an
11-bit main divider ratio with 8/9 prescaler
Note 1: These bits must be programmed after power is applied to the device. Failure to do so may result in erroneous device operation.
