Converter Electrical Characteristics
The following specifications apply after calibration for V_A = V_DR = +1.9V; OutV = 1.9V; V_IN FSR (a.c. coupled) = differential 870
mV_P-P; C_L = 10 pF; Differential, a.c. coupled Sine Wave Input Clock, f_CLK = 1.5 GHz at 0.5 V_P-P with 50% duty cycle; V_BG = Floating;
Non-extended Control Mode; SDR Mode; R_EXT = 3300 Ω ±0.1%; Analog Signal Source Impedance = 100 Ω Differential; 1:2 De-
multiplex Mode; Duty Cycle Stabilizer on. Boldface limits apply for T_A = T_MIN to T_MAX. All other limits T_A = 25°C, unless otherwise
noted. (Note 6, Note 7, Note 16, Note 18)
