Specifications subject to change without notice.
AC specs based on an analog input voltage of –0.5 dBFS at 10.3 MHz unless otherwise noted. AC specs for -40, -80, -105 grades are tested in 1 V p-p range and
driven differentially. AC specs for -65 grade are tested in 2 V p-p range and driven differentially.
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.
