ML6430/ML6431
DEVICE DIFFERENCES
Tables 1 and 2 summarize the differences between the
ML6430 and ML6431. The pinouts of the ML6430 and the
ML6431 are the same with the exception that the ML6431
has a few enhancements, (Center Frequency and Free Run
Mode, see Table 1) and added functionality (see Table 2).
