Notes:
1. Parameter is guaranteed by design and characterization. Not 100% tested in production.
2. Input Reference Frequency = 25 kHz, Output Frequency = 25 MHz. Jitter measured between adjacent vertical pixels.
3. CLK1 frequency applies for FS = 0. For FS = 1 condition, divide allowable CLK1 range by the factor of 4.
4. An Application Brief (AB01) documents the operation of the AV9173 for low input frequencies. This provides
guidelines for usable output frequencies and feedback ratios required to use inputs below 25 kHz. By following these
guidelines, the AV9173 will operate down to 12 kHz inputs across temperature, voltage and lot-to-lot variation.
