Part Number: CDCEL913
Hi,
I'm designing a clock source block for wearable device. I need 3 output frequencies: 2.048MHz, 4.096MHz and 32000kHz. I can feed 8.000MHz in Xin input pin by means of a CPU pin outputting 8.000MHz. I chose the CDCEL913 because I need that all the frequencies are syncronized. I want to minimize supply current to the CDCEL913. In the datasheet table 5.5 I read that fvco must be greather or equal to 80MHz, while in the figure 5.1 I see that fvco frequency is in the range 10MHz - 230MHz.
I'm wondering if I could use fvco as low as 10MHz in order to make the supply current around few mA or less. If not, what is the minimum fvco allowed for reliable CDCEL913 operation ?
Thanks,
Luca
