1 AC specifications based on an analog input voltage of –0.5 dBFS at 10.3 MHz, unless otherwise noted. AC specifications for 40, 80, 105 grades are tested in 1 V p-p
range and driven differentially. AC specifications for 65 grade are tested in 2 V p-p range and driven differentially.
2 The 65, 80, and 105 grades are tested close to Nyquist for that grade: 31 MHz, 39 MHz, and 51 MHz for the 65, 80, and 105 grades, respectively.
