CDCE949-Q1: Create the various voltage and frequency

Part Number: CDCE949-Q1

I would like to create various clocks by clock generator. I guess this device CDCE949-Q1 is close to the correct as far as I searched. 

I would like the solution which can handle various clocks of voltage (1.0Vpp, 1.8Vpp and 3.3Vpp) and frequency (26 MHz, 32.76 kHz, 40MHz and etc) at the same time.Additionally I want more than 7 clocks. CDCE949-Q1 can supply 9 clock sof 3.3Vpp. But it can't supply 1.0Vpp and 1.8Vpp as far as I searched. I guess the combination of  CDCE949-Q1 and level sifters enable it. 

Please tell me your opinion about this solution of the combination of  CDCE949-Q1 and level sifters.

Could you tell me another TI's great solution? The solution with any other clock generator is OK because I don't stick to CDCE949-Q1

  • Hi Taito,

    The downside level shifting can be handled by simple resistor dividers. For example, this can divide the 3.3V CMOS down to 1.8V:

    If output current is concern, consider using DC block to eliminate the DC current.
