The I2C-OSC board is an 8-pin CMOS
1KHz – 68MHz Programmable Oscillator
device using I
external components required. Only two
signal lines SDA and SCL plus supply
voltage and ground are required to be
connected. This makes it perfect for
embedded
programmable oscillator.
This board features innovations that set it
apart from other programmable oscillator
module. Innovations feature like on-board
I
and power LED. The module can be
quickly connected directly on to the
breadboard. The board is small and
compact in size 0.70 x 0.61 inches.
The I2C-OSC is designed base on
LTC6904 IC. It is a low power self
contained digital frequency sources
providing a precision frequency from
1KHz to 68MHz, set through an I
operates over a single wide supply range
of 2.7V to 5.5V.
The LTC6904 feature a proprietary
feedback loop that linearizes the
relationship between digital control setting
and frequency, resulting in a very simple
frequency setting equation:
A jumper pins vary the fixed I
and allow up to two I2C-OSC to share the
same I
