Product overview
SYN3305A The miniature timing equipment is a highly accurate quartz crystal frequency standard designed and developed by Xi'an synchronous Electronic Technology Co., Ltd.The OCX0 constant temperature crystal oscillator is installed inside. The GPS/ Beidou timing signal is used to lock the constant temperature crystal oscillator, so that the output frequency and time of the machine can keep pace with the GPS.When the internal PLL works normally, the product can automatically learn the phase-locked process and automatically resume the process after GPS is lost.It is possible to maintain the state of the lock before disconnecting the external reference for a long time.
Key word Time synchronization, PTP master clock, B code timing system, time synchronization terminal.
Product function
1) Beidou /GPS signal is used as external time reference signal;
2) Generate B codes (DC), 1MHz, 5MHz, 10MHz, etc.
3) Generate 2 second pulse and 1 serial port time.
4) PTP Network timing function;
Product characteristics
A) High precision, fully automatic, unattended, maintenance free, low power consumption and high reliability.
B) Stable and reliable IRIG-B AC code receiving and decoding function;
C) The main signal input and output circuit adopts electrical isolation circuit, which is anti-interference and anti damage.
D) The output interface signals are complete, and the output signals can be flexibly configured according to users' needs.
E) Wide working temperature range can work steadily for a long time.
Typical application
1) National defense research;
