ADC DRIVING APPLICATION
The ADL5535 is a high linearity, fixed gain IF amplifier suitable
for use as an ADC driver. Figure 22 shows the schematic of the
ADL5535 driving the AD9268 16-bit analog-to-digital converter
(ADC). The ADL5535 has a single-ended input and output imped-
ance of 50 Ω. A 1:1 impedance transformer, along with termination
resistors and series ferrite beads, are used to present a 50 Ω load
for the antialiasing filter interface. The filter interface between the
ADL5535 and the AD9268 is a sixth-order Butterworth low-pass
filter. The interface provides a 50 MHz, 1 dB bandwidth centered
around 175 MHz. Following the sixth-order filter, a shunt LC tank
circuit was inserted to further reduce the low frequency response
of the filter, giving more of a band-pass response to the filter.
The normalized wideband response is shown in Figure 19.
