Question

The frequency of 101 series is. ​

Answer 1

Frequency references are an essential part of a radio. One critical function is to provide an input clock to a PLL which allows the radio to receive and transmit at a precise frequency. The reference frequency accuracy required to meet the Bluetooth low energy (BLE) standard is +/-50 ppm (parts per million) and +/-40 ppm for ZigBee. Also, the Bluetooth Low Energy specification requires the initial transmitted center frequency to be accurate to +/-75kHz. If the transmitter is broadcasting at a frequency less accurate than this, the receiver will not be able to receive the data. To give you an idea of what 40 ppm accuracy means, imagine counting the seconds for an entire day and only being off by four at the end. This may sound like a very tight accuracy requirement, but compared to some standards, it's quite loose. If you were counting the seconds, you’d need to count for 115 days and be off by only one to meet the frequency synchronization requirements between a GSM handset and basestation.
