CONVERTER ELECTRICAL CHARACTERISTICS (continued)
The following specifications apply after calibration for VA = VDR = +1.9VDC, OutV = 1.9V, VIN FSR (a.c. coupled) = differential
820mVP-P, CL = 10 pF, Differential a.c. coupled Sinewave Input Clock, fCLK = 1.5GHz at 0.5VP-P with 50% duty cycle, VBG =
Floating, Non-Extended Control Mode, SDR Mode, REXT = 3300Ω ±0.1%, Analog Signal Source Impedance = 100Ω
Differential, after calibration. Boldface limits apply for TA = TMIN to TMAX. All other limits TA = 25°C, unless otherwise noted.
