Wideband Input Amplifier
Typical Operating Characteristics
(AV_CC = AV_CCI = AV_CCQ = AV_CCR = +5V, OV_CCI = OV_CCQ = +3.3V, AGND = AGNDI = AGNDQ = AGNDR = 0, OGNDI = OGNDQ = 0,
f_CLK = 802.816MHz, differential input at -0.5dB FS, C_L = 1µF to AGND at REF, R_L = 100Ω ±1% applied to digital LVDS outputs, T_A =
T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C)
