Embodiment Construction
[0025] The invention provides a crystal-compatible circuit board and its circuit. Aiming at the limited space of the circuit board and the shortage of resources, circuits and circuits compatible with more crystal sizes are designed to maximize the utilization of cost and resources. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] Please also see figure 2 and image 3 The crystal compatible circuit board provided by the present invention is provided with a crystal pad for welding single crystal or double crystal, and several device pads for welding peripheral circuit devices of single crystal and double crystal. The plurality of devi...

The invention discloses a circuit board compatible with a crystal, and a circuit thereof. The circuit board comprises a CPU bonding pad and a CPU crystal oscillator bonding pad. The circuit board also comprises a crystal bonding pad for welding a single crystal or bicrystal, and a plurality of device bonding pads for welding single crystal and bicrystal peripheral circuits. The plurality of device bonding pads are connected with the crystal bonding pad through wires, and the crystal bonding pad is connected with the CPU bonding pad and the CPU crystal oscillator bonding pad. Because only one crystal bonding pad is set and the device bonding pads for the single crystal and bicrystal peripheral circuits are set at the same time, the single crystal or bicrystal for welding can be welded on the crystal bonding pad according to the actual needs. A corresponding device is selected for welding pasters on the device bonding pads or suspension, thereby forming a peripheral circuit corresponding to the crystal. One circuit board can be compatible with the single crystal and bicrystal and the peripheral circuits thereof. Compared with the prior art, the circuit board reduces one crystal and the corresponding peripheral circuit thereof, saves the space, and reduces the material and cost.
Description
technical field [0001] The invention relates to the technical field of X-ray machine movement, in particular to a crystal-compatible circuit board and its circuit. Background technique [0002] With the rapid development of GPS (Global Positioning System, Global Positioning System), WLAN (Wireless Local Area Network), LTE (Long Term Evolution, long-term evolution) and other technologies, high-performance crystals with excellent long-term and short-term frequency stability for radio frequency communication systems Demand for oscillators has also skyrocketed. Because the temperature compensated crystal oscillator (TCXO, referred to as crystal oscillator) is one of the key devices in the radio frequency circuit of portable communication terminals such as mobile phones, it includes a voltage-controlled temperature-compensated crystal oscillator (VCTCXO, referred to as temperature-compensated crystal with voltage-controlled frequency correction function) ) can cooperate with the...
