Maximum Operation Frequency For CY7B994V RoboClockII
Question: The data sheet shows the maximum of the CY7B994V FS HIGH range as 200 MHz but the f'OUT specification has a 185 MHz maximum. Is there a contradiction here?
No. The maximum output frequency allowed with RoboClockII is 185 MHz. However, the internal VCO is allowed to run up to 200 MHz. For example, you could have a reference input of 20 MHz with a /10 FB. The internal VCO would be operating at 200 MHz. In this scenario a /1 output is illegal since that would require the output buffer to operate at 200 MHz. The minimum divide ratio on the output banks in this instance would be /2.
