The large-scale production of quantization.The volume of constant-temperature crystal oscillator is constantly subjected to limit due to the particularity of product, its volume and structure
System, contradiction is formd with the demand for development of electronic technology.This new design is aiming at this situation, a kind of paster structure of exploitation
The constant-temperature crystal oscillator product for being suitable for mass, small size.
The content of the invention
To solve the above problems, the present invention provides a kind of small size patch shape constant-temperature crystal oscillator.
Technical scheme is specially：
A kind of small size patch shape constant-temperature crystal oscillator：Main vibration circuit connects amplifying circuit, and amplifying circuit connects output circuit,
Temperature control circuit connects main vibration circuit, and regulator circuit connects temperature control circuit, main vibration circuit, amplifying circuit, power circuit connection respectively
Regulator circuit and output circuit, foregoing circuit are encapsulated as constant-temperature crystal oscillator using SMD device architectures, and package casing is using high
Directional thermal decomposition graphite, the housing exterior wind basalt fibre net.
Further：Input interface and output interface are arranged in oscillator both ends, and all input interfaces are placed on the same end,
All output interfaces are placed on the other end.
Further：It is packaged using standard DIP14 sizes.
Relative to the prior art, technique effect of the invention is, using the SMD device architectures of standard DIP14 sizes, to produce
In the case that product index is not less than similar product, to provide the bar using automatic chip mounting production equipment using the user of this product
Part.The use of SMD device architectures produces easy to the automatic chip mounting of high stable crystal oscillator, and advantage is created for mass production.
SMD device architectures effectively reduce the encapsulation volume of oscillator, have widened use scope, promote the miniaturization of electronic technology
Development.

End, and all input interfaces are placed on the same end, and all output interfaces are placed on the other end.
The both ends for outputting and inputting interface and being arranged in whole oscillator, the oscillator center section when carrying out original paper layout
There is no the interference of external interface, layout and wiring easy to original paper.
All in oscillator one end and output interface layout in the other end, such distribution form reduces layout input interface
Original paper wiring difficulty, input line concentrates one end and output line concentrates on the other end, avoid between input line and output line
Interfere with each other, stabilizer and reliability when improving oscillator operation.
The present invention is packaged using standard DIP14 sizes, is suitable for industrialized batch production.
The technical indicator of the present invention is as follows：
（1）Product design size：Long 22mm, wide 12mm, high 6--10mm.
（2）5V, 3.3V power.
（3）Temperature stability meets in-40-70 DEG C, better than 20ppb.
（4）Ageing Index meets 1ppb/day
（5）Phase noise is better than -145dbc/Hz@1kHz
（6）SMD device architectures patch encapsulates.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
