Phase Noise(typical)


Reference clock module for PCK3GF-1


PCK3GF-1 and REF10MF have been mounted on a board and born as a signal generator PGN3GF-1


GPS disciplined 10MHz TCXO, REF10MF and PCK3GF-1 have been mounted on a board and born as a signal generator GPSG-3G.

As a signal source, desired clock sinals can be generated with 1 KHz resolution in an extremely wide band of 25MHz to 3000MHz. The frequency is set with asynchronous serial data. Also, the frequency can be set by SPI serial data. Once frequency is successfully set, the frequency is automatically memorized into EEPROM. At the next power on, the last entered frequency is retrieved. Frequency stability and accuracy depends on external clock source.
