CY22050 Frequency Ranges

Question: What are the minimum and maximum frequency ranges for the CY22050?

 

Answer:

The input frequency range is 8-30MHz crystal, 1-133MHz driven for all Commercial as well as Industrial versions.

Output Frequency Range:

CY22050 - Commercial - 800KHz - 200MHz (3.3V) and 800KHz - 166.6MHz (2.5V)
CY22050 - Industrial - 800KHz - 166.6MHz (3.3V) and 800KHz - 150 MHz (2.5V)

 

Note: 8KHz can only be obtained from the buffered 1MHz reference divided by 127 (Maximum output divider value).

 

PLL Frequency Range:

 

CY22050 - Commercial - 100MHz - 400MHz

CY22050 - Industrial - 125MHz - 332MHz

 

The frequency ranges are reduced at higher temperatures for guaranteed PLL stability. The PLLs do not reliably lock at higher temperatures for which the margins are reduced.
