Satellite-Synchronized Clock(GPS)

Key Features:

?The DF540 Satelite Synchronized Clock can be Synchronized by two time sources:GPS antenna or IRIG-B code Normally the device is synchronized by GPS, in case of GPS antenna time signal losses, it can also be synchronized by the input of IRIG-B signal from other GPS clock source.

◆The device equipped with an internal TCXO(Temperature Compensated Crystal ocillator) with a long term GPS oscillator disciplining algorithm. When the two time sources(GPS or IRIG-B) both unavailable, the device can be clocked by the internal high accuracy TCXO.

◆The device provides NTP/SNTP service with two 10/100M adaptive Ethermnet interface, support two independent IP address.

?The device has a dedicated input port for measuring the frequency of AC power network.

?On the front panel, an 2* 16 alphanumeric LCD panel displays time, date and power frequency information. The status of the system is shown by seven LEDs (power supply, PPS signal, PPM signal, Time source, Time source alarm).

?The GPS can be configured by software.

?The rear face of the equipment equipped with all the input/output signals,the device provide various outputs:

-PPS,PPM,PPH;

Up to 13 RS422 for IRIG-B code output;

Up to 12 Optical fiber for IRIG-B non-modulated output;

Up to 12 RS422 serial output for time frame periodic transmission;

-Up to 13 RS232 serial output for time frame periodic transmission;

-Up to 6 Ethernet port used for NTP;

?All inputs/outputs are isolated with each other and equipped with protection circuit

?The device is 19" wide and 2U high and can be flush mount in standard cubicle.
