Why Customers Choose “Clock Generator”

Have you ever wanted to use a "clock generator" that can output "multiple" frequencies instead of a "single oscillator"?

The biggest advantage of using a clock generator is that it eliminates the need for multiple clock devices (oscillators and oscillators) when seeking "optimization" depending on the device you want to drive and circuit configuration. This reduction in the number of parts brings about various effects such as "cost reduction of BOM", "BCP measures", and "reduction of board area". For that reason, many customers have adopted the "Clock Generator".

"Four selections" of customer concerns in selecting a clock generator

"Clock generators" have many advantages as described above, but in talking with various customers, we often receive the following inquiries, and it seems that the selection of a clock generator is often not straightforward. is.

1. "Compared to an oscillator, it's a little more complicated, so I'm using the one I used before, but I'm worried about the 'variation in frequency.'"

2. "The characteristics of the external oscillator are not good, and it does not work as expected."
3. "The device that was previously used has reached EOL."
Four. "It is very difficult to obtain, including market products."

If you try SiTime's "Clock Generator", you can solve various problems for such customers.

SiTime Clock Generator

SiTime's "Clock Generator" has the following features, and can provide solutions to the "four problems + α" that are common to customers mentioned above.

・Built-in MEMS resonator

→ You can reduce the number of external oscillators required for conventional products.

This eliminates the influence of oscillator specs and variations.

Reducing the number of parts also brings benefits in terms of cost and procurement.

In addition, it is possible to reduce the cost and man-hours that would otherwise be incurred by suppressing the risk of defects caused by the oscillator.

・Built-in 4 PLLs (decimal point)

→ You can freely set the settings according to your desired specifications.

・Excellent jitter performance

→ We offer products with excellent specifications that meet the strict jitter requirements required by the devices to be driven.

・Compatible with spread spectrum (planned)

→ Measures against EMI noise can be easily implemented.

- No external memory required

→ Write to the internal one-time memory to achieve the desired operation (I2C programmable)
