VPS, VPI, VPSD = 3.3 V, TA = 25°C, ZLOAD = 400 Ω, power mode bit (B9) = 0 (low power mode), digital gain code bits (B8 to B2) = 1111110, dc offset disable bit (B1) = 0 (enabled), filter corner = 63 MHz, ac coupling mode, fundamental at 31 MHz, unless otherwise noted. For HD2/HD3 vs. gain plots: 1.5 V p-p output target level, and reference Figure 67 for analog gain distribution.
