Frequently Asked Questions
Common questions about XHTF1040B CPT Atomic Clock
What makes the XHTF1040B suitable for high-dynamic platforms?
The XHTF1040B pairs a miniature structure with 1PPS input synchronization and TOD short-message output and is optimized for high-dynamic situations. Its SA.45-compatible pinout and UART serial interface simplify drop-in integration.
What phase noise does the XHTF1040B achieve?
Its single-sideband phase noise on the 10 MHz output is -90 dBc/Hz at 10 Hz, -120 dBc/Hz at 100 Hz, -140 dBc/Hz at 1 kHz, and -145 dBc/Hz at 10 kHz.
What power supply and interface does the XHTF1040B use?
It runs from a 3.3 V low-power supply and communicates over a UART serial port, providing 1PPS input and output, a 10 MHz output, and a lock-status line on an SA.45-compatible connector.
Where is the XHTF1040B typically used?
It is assembled into time-frequency systems for satellite navigation, underwater navigation, digital communication, network synchronization, and railway transportation.
