The LTC
6903/LTC6904 are low power self contained
digital frequency sources providing a precision frequency
from 1kHz to 68MHz, set through a serial port. The
LTC6903/LTC6904 require no external componentsother
than a power supply bypass capacitor, and they operate
over a single wide supply range of 2.7V to 5.5V.
The LTC6903/LTC6904 feature a proprietary feedback
loop that linearizes the relationship between digital control
setting and frequency, resulting in a very simple frequency
setting equation:
Hz
DAC
1024
Where OCT is a 4-bit digital code and DAC is a 10-bit digital
code.
The LTC6903 is controlled by a convenient SPI compatible
serial interface. The LTC6904 uses an industry standard
