Crystal or Crystal Oscillator?

clk crystal oscillator

i am using hyperStone 16xRS DSP/RISC chip needs 16 MHz.

which crystal can i use? a Crystal oscillator(4 pin) or Quartz Crystal(2 pin) ?

and what is the differences between a CRYSTAL OSCILLATOR and a QUARTZ CRYSTAL?

A Crystal oscillator(4 pin):
the 4 pin includ: power,ground,clk out.If power is on,the pin clk out will work.

A Quartz Crystal(2 pin):
the 2 pin includ:clk in,clk out.

oscillator generate clock by itself, while crystal need other components (cap and active devices) to construct an oscillator. many MCUs can use both. check your datasheet.

i got it thank you!

However for higher fan-out you need to use clock buffers.
