Hello everyone, in this lesson we will talk about the code name of the crystal oscillator

2

00:00:06,466 --> 00:00:10,933

Crystal oscillators are generally represented by X or Y

3

00:00:11,600 --> 00:00:14,300

For example, the physical picture on the left, Y8

4

00:00:14,866 --> 00:00:21,366

Where Y indicates that this component is a crystal oscillator

5

00:00:21,933 --> 00:00:26,333

8 means that the number of this crystal oscillator is 8

6

00:00:27,566 --> 00:00:30,933

Another example in the circuit diagram on the right, X2601

7

00:00:31,300 --> 00:00:39,900

Where X represents that this component is a crystal oscillator

8

00:00:40,600 --> 00:00:46,600

2601 represents the number of the crystal oscillator is 2601

9

00:00:48,500 --> 00:00:52,666

Next, let's talk about the circuit symbol of the crystal oscillator

10

00:00:53,333 --> 00:00:58,566

The circuit symbol of the crystal oscillator well reflects the structure of the crystal oscillator

11

00:00:59,266 --> 00:01:05,433

As we said before, the crystal oscillator is made of a quartz crystal plated

12

00:01:05,866 --> 00:01:09,733

with electrodes and drawn out from the pins.

13

00:01:10,666 --> 00:01:17,866

In the middle of the circuit symbol is the quartz crystal, on both sides are the plated electrodes,

14

00:01:19,333 --> 00:01:22,900

and next to it are the lead-out pins
