Programmable crystal oscillator clock
2011
The utility model relates to a programmable clock crystal oscillator which comprises a crystal oscillator, a programmable logic control circuit and a signal buffer circuit, wherein the crystal oscillator, the programmable logic control circuit and the signal buffer circuit are sequentially electrically connected with each other; and the crystal oscillator generates clock precision indexes required by the user. The precision of the precision clock is implemented by using the programmable logic chip; since the output frequency of the utility model can be transformed by the programmable logic control circuit, the utility model is especially suitable for special output frequencies; and the utility model can ensure the product precision and implement quick delivery of products, thereby greatly enhancing the market response speed.
