Rx ADC inputs only requires half the signal swing com-
pared to single-ended mode. Figure 10 shows an RF
transformer converting the MAX19713 Tx DAC differen-
tial analog outputs to single-ended.
Using Op-Amp Coupling
Drive the MAX19713 Rx ADC with op amps when a
balun transformer is not available. Figures 11 and 12
show the Rx ADC being driven by op amps for AC-cou-
pled single-ended and DC-coupled differential applica-
tions. Amplifiers such as the MAX4454 and MAX4354
provide high speed, high bandwidth, low noise, and
low distortion to maintain the input signal integrity. The
op-amp circuit shown in Figure 12 can also be used to
interface with the Tx DAC differential analog outputs to
provide gain or buffering. The Tx DAC differential ana-
log outputs cannot be used in single-ended mode
because of the internally generated common-mode
level. Also, the Tx DAC analog outputs are designed to
drive a differential input stage with input impedance ≥
70k
Ω. If single-ended outputs are desired, use an
amplifier to provide differential-to-single-ended conver-
sion and select an amplifier with proper input common-
mode voltage range.
FDD Application
Figure 13 illustrates a typical FDD application circuit. The
MAX19713 interfaces directly with the radio front-ends to
provide a complete “RF-to-Bits” solution for FDD applica-
tions such as 802.11, 802.16, WCDMA, and proprietary
radio systems. The MAX19713 provides several system
benefits to digital baseband developers:
Fast Time-to-Market
High-Performance, Low-Power Analog Functions
Low-Risk, Proven Analog Front-End Solution
No Mixed-Signal Test Times
No NRE Charges
No IP Royalty Charges
Enables Digital Baseband and Scale with 65nm to
90nm CMOS
Grounding, Bypassing, and
Board Layout
The MAX19713 requires high-speed board layout design
techniques. Refer to the MAX19713 EV kit data sheet for a
board layout reference. Place all bypass capacitors as
close to the device as possible, preferably on the same
side of the board as the device, using surface-mount
devices for minimum inductance. Bypass VDD to GND
with a 0.1F ceramic capacitor in parallel with a 2.2F
capacitor. Bypass OVDD to OGND with a 0.1F ceramic
