6 AC ELECTRICAL CHARACTERIS TICS
The AC electrical characteristics listed in Table 3 are valid for the following
conditions unless otherwise noted. Typical parameters are at T_A = +25°C.
• V_CC = +4.75V to +5.25V
• TXEN = SHDN = high
• D7 = 1
• V_IN = 33 dBmV differential
• Output impedance = 75Ω through a 4:1 impedance transformer
• T_A = -40°C to +85°C
