Attribute Definitions
FIGURE 2: FREQUENCY/CHANNEL (DB0 - DB23) This is a 24 bit string used to set the synthesizer’s
START Frequency, STOP Frequency, STEP Frequency, REF Frequency or CHANNEL number.
FIGURE 3: MULTIPLIER (DB24 - DB27) The data in FREQUENCY/CHANNEL (DB0-DB23) is multiplied
by 10
FIGURE 4: FUNCTION SELECT (DB28 - DB31). After the data in FREQUENCY/CHANNEL (DB0 - DB23)
is multiplied by 10
routed internally to the START, STOP, STEP, REF or CHANNEL registers based on the contents of FUNC-
TION SELECT as shown below.
