FREQUENCY AND PHASE PAGES (PAGES 0 AND 1)
Pages 0 and 1 are used to set the tuning frequencies and phase offsets of the four channels. Page 0 also contains the read
only checksum diagnostic register and the mask revision register.
The 32 bit frequency control word is defined as:
FREQ = 2
32
F/F
CK
where F is the desired tuning frequency
and F
CK
is the chip’s clock rate (not the CK2X rate). Use positive frequency values to upconvert signals. Use negative frequency
values to upconvert inverted spectrums. The 32 bit 2’s complement frequency words are entered as four bytes, the least
significant byte in the lowest address, the most significant in the highest address.
The 16 bit phase offset is defined as:
PHASE = 2
16
P/2
π
where P is the desired phase in radians from 0 to 2
π
.
PAGE 0: Channels A and B
ADDRESSES 16, 17, 18, and 19: Frequency Channel A
ADDRESSES 20, 21: Phase Channel A
ADDRESSES 24, 25, 26, and 27: Frequency Channel B
ADDRESSES 28, 29: Phase Channel B
ADDRESSES 30, 31: Checksum and Revision Registers
