ADL5565
Data Sheet
ADC INTERFACING
The ADL5565 is a high output linearity amplifier that is optimized
for ADC interfacing. There are several options available to the
designer when using the ADL5565. Figure 40 uses a wideband
1:1 transmission line balun followed by two 40 resistors in
parallel with the three input impedances (which change with
the gain selection of the ADL5565) to provide a 50
differential impedance and provides a wideband match to a
50 source. The ADL5565 is ac-coupled from the AD9467 to
avoid common-mode dc loading. The 33 resistors improve the
isolation between the ADL5565 and any switching currents
present at the analog-to-digital, sample-and-hold circuitry. The
AD9467 input presents a 530 differential load impedance and
requires a 2 V to 2.5 V differential input swing to reach full scale
(VREF = 1 V to 1.25 V). This circuit provides variable gain,
isolation, and source matching for the AD9467.
Applying a full-scale, single-tone signal from the ADL5565, an
SFDR of 91.9 dBc is realized (see Figure 37). Applying two half-
scale signals from the ADL5565 in a gain of 6 dB, an SFDR of
86.4 dBc is achieved at 100 MHz (see Figure 38). The bandwidth
of the circuit in Figure 40 is shown in Figure 39.

Figure 39. Measured Frequency Response of the Wideband
ADC Interface Depicted in Figure 40
The wideband frequency response is an advantage in broad-
band applications, such as predistortion receiver designs and
instrumentation applications. However, by designing for a wide
analog input frequency range, the cascaded SNR performance is
somewhat degraded due to high frequency noise aliasing into
the wanted Nyquist zone.
