What are the commonly used crystals for wireless mouse and Bluetooth mouse?

the crystal oscillator application in wireless

As we all know, the mouse as a computer peripheral is an essential aid for desktop computers, laptops and even tablet PCs. Therefore, we want a mouse in our hands that is responsive and durable. With the rapid changes in technology, more and more traditional wired mice have been gradually replaced by wireless mice. According to the signal coding way is different, wireless mouse, Bluetooth mouse, wireless mouse are divided into 2.4G band wireless mouse and Bluetooth mouse two categories. 

Wireless mouse and Bluetooth mouse work on different principles.

The difference between a wireless mouse and a Bluetooth mouse

A wireless mouse requires a receiver to be plugged into the USB port of the computer and the signal radiation range is around 3 meters. The distance is limited and there is a possibility that the data transmission will be interfered with by external signals.

Bluetooth mouse does not need a receiver, but the computer must be built-in Bluetooth module, the effective range of signal radiation up to 10 meters, and signal transmission with strong stability.

So, what are the commonly crystal oscillator application in these two goods?

Wireless mouse: 4Mhz, 6Mhz, 12Mhz

Bluetooth mouse: 16Mhz, 32Mhz

PS: At present, Bluetooth mouse using the mainstream crystal package and size to SMD3225 mainly, small 2520 package is less.The characteristics of crystal for the mouse: stable output frequency, low latency, low power consumption.
