ICS9173B

REV D 012913

AC Electrical Characteristics

Unless stated otherwise, VDD = 5 V ±5%, Ambient Temperature 0 to +70

 C

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 ICS9173B will operate down to 12 kHz inputs across temperature, voltage and lot-to-lot

variation.

5. Jitter values are measured at frequencies > 25 MHz for IDT9173B-01, for ICS9173B-15, jitter is measured at

frequency > 12.5 MHz.
