FEATURES
s s s s DESCRIPTIO s s s s s s s s 1kHz to 68MHz Square Wave Output 0.5% (Typ) Initial Frequency Accuracy Frequency Error <1.1% Over All Settings 10ppm/°C Typical Frequency Drift Over Temperature 0.1% Resolution 1.7mA Typical Supply Current (f < 1MHz, VS = 2.7V) 2.7V to 5.5V Single Supply Operation Jitter <0.4% Typical 1kHz to 8MHz Easy to Use SPI (LTC6903) or I2C (LTC6904) Serial Interface Output Enable Pin –40°C to 125°C Operation MS8 Package 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 components other 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: 2078(Hz) f = 2OCT● ;1kHz < f < 68MHz DAC 2 – 1024 Where OCT is a 4-bit digital code and DAC is a 10-bit digital code.
