10 MHz-Ref.-Osc. V2.1 by DF4IAH
This module is a GPS assisted 10 MHz reference oscillator generating a very stable 10 MHz frequency which is pulled by the determination of frequency and phase errors based on the 1PPS signal of the GPS receiver chip. The oscillator is a VCTCXO, that means it is a voltage pull-able high precision frequency generator, that is temperature compensated for higher frequency stability.
The USB connector is used for power supply and data communication. Additionally a LCD module can be attached to the I2C port. The matching LCD module is listed in the SPECIFICATION tab.
The power consumption with attached LCD module and activated backlight draws about 155 mA @ 5 volts. That is a low consumption compared to other designs. The current can be minimized to about 40 mA when the display is disconnected.
