reference locking for amateur radio communications devices

Uses ADF4153/7 fractional N synthesiser to deal with very low highest-common-factors such as locking a FT-1000 10.485760 MHz to 10MHz.

Tiny form factor - maintains same form factor as XREF product 13.6 x 29.1mm

All components machine loaded. 107 parts , over two sides on 4 layer PCB.

Ample solder-blob jumpers to deal with input options.

8-15V input

USB interface for programming and configuration.

free run of existing TCXO when external provided reference not present

LED multi status indicator .

Handles variety of internal reference amplitudes with on board amplifier for < 100 MHz inputs .

Requires >= +2dBm reference input 10 to 150 MHz (10 MHz nominal)

control output able to pull power supplies as well as VCXO inputs.

Low loop filter BW preserves existing internal reference noise performance and excludes fractional spurs.
