There are no output external components required. Only two 0.5% (Typ) initial frequency signal lines SDA and SCL plus supply accuracy voltage and ground are required to be Frequency error <1.1% over all connected. This makes it perfect for settings embedded systems that require 0.1% resolution programmable oscillator. Jitter < 0.4% typical 1KHz to 8MHz 2 I C Interface up to 3.4 Mbps This board features innovations that set it Stand alone module, no external apart from other programmable oscillator components required module. Innovations feature like on-board 2 On-board IC address jumpers, 2 IC address jumpers, pull-up resistors, pull-up resistors and power LED and power LED. The module can be Decoupling supply voltage quickly connected directly on to the Design easy for breadboard breadboard. The board is small and High quality double sided PCB compact in size 0.70 x 0.61 inches. All SMT components Small and compact in size 0.70 x The I2C-OSC is designed base on 0.61 inches LTC6904 IC. It is a low power self Dual row 0.6 width, 0.1 pitch contained digital frequency sources header pins providing a precision frequency from 2 1KHz to 68MHz, set through an I C bys. It Flexible operating power supply voltage range of +2.7V to +5.5V operates over a single wide supply range of 2.7V to 5.5V. Suitable for 3.3V or 5.0V microcontroller The LTC6904 feature a proprietary feedback loop that linearizes the relationship between digital control setting Applications and frequency, resulting in a very simple frequency setting equation: Precision Digitally Controlled Oscillator Power Management Direct Digital Frequency Synthesis (DDS) Replacement 2 Switched Capacitor Filter Clock A jumper pins vary the fixed I C address And much more and allow up to two I2C-OSC to share the 2 same I C bus. 2 * I C is a trademark of Philips Semiconductors Corporation.
