1, what is the difference of crystal
As the name suggests is the output differential signal oscillator, differential oscillator refers to output differential signal using 2 phase signal exactly opposite to each other, thus eliminating the common mode noise, and produce a high performance system. Many high-performance protocols use differential signals such as SATA, SAS, optical fiber communications, 10G Ethernet, and so on
2, the difference of crystal package commonly used what
At present, the mainstream of the market difference is 6 foot crystal chip packaging, common sizes are 7050 and 5032, 3225 volumes of course SiTime can also provide smaller.
3, the difference of the crystal effect
Differential oscillator is generally stable clock signal is FPGA or CPLD, FPGA or CPLD because they are expensive, so choose a stable difference necessary sub crystal. In addition to the output signal model, the rest of the parameters and the general active crystal almost.
4, differential oscillator which parameters need to purchase
First of all, to confirm the good frequency, and then the voltage, the package volume, operating temperature and frequency stability (precision ppm). For detailed specifications, can also be sent to Tritace reference specification.
5, application field of the crystal
Applied to Gigabit Ethernet, fibre channel, SAS, PCI Express server, network, storage, router / switch, optical transmission equipment, etc..
6, the benefits of differential oscillator
It is easy to identify small signal.
External electromagnetic interference (EMI) is highly immune.
Able to deal with the 'bipolar' signal.
7, the difference in parameter of crystal oscillator
The frequency range: 10 - 425.0000MHZ of arbitrary frequency, and accurate to a decimal point after six.
Voltage: 2.25V, 2.5V, 3.0V, 3.3V, 3.6V can be arbitrarily selected applications.
Specification: 7050(7.0*5.0mm) 5032(5.0*3.2mm) 3225(3.2*2.5mm)
