MAX107
Grounding, Bypassing,
and Board Layout
Grounding and power supply decoupling strongly influ-
ence the MAX107’s performance. At 400MHz clock fre-
quency and 6-bit resolution, unwanted digital crosstalk
may couple through the input, reference, power supply,
ground connections, and adversely influence the
dynamic performance of the ADC. In addition, the I&Q
inputs may crosstalk through poorly designed decou-
pling circuits. Therefore, closely follow the grounding
and power-supply decoupling guidelines in Figure 9.
Maxim strongly recommends using a multilayer printed
circuit board (PC board) with separate ground and
power supply planes. Since the MAX107 has separate
analog and digital ground connections (AGND, AGNDI,
AGNDQ, AGNDR, OGNDI, and OGNDQ, respectively).
The PC board should feature separate sections desig-
nated to analog (AGND) and digital (OGND), connect-
ed at only one point. Digital signals should run above
the digital ground plane and analog signals should run
above the analog ground plane. Keep digital signals far
away from the sensitive analog inputs, reference inputs,
and clock inputs. High-speed signals, including clocks,
analog inputs, and digital outputs, should be routed on
50
microstrip lines, such as those employed on the
MAX105EV kit.
The MAX107 has separate analog and digital power-
supply inputs:
AVCC = +5V ±5%: Power supply for the analog
input section of the clock circuit.
AVCCI = +5V ±5%: Power supply for the I-channel
common-mode buffer, pre-amp and quantizer.
AVCCQ = +5V ±5%: Power supply for the Q-chan-
nel common-mode buffer, pre-amp and quantizer.
AVCCR = +5V ±5%: Power supply for the on-chip
bandgap reference.
OVCCI = +3.3V ±10%: Power supply for the I-chan-
nel output drivers and DREADY circuitry.
OVCCQ = +3.3V ±10%: Power supply for the
Q-channel output drivers and DOR circuitry.
All supplies should be decoupled with large tantalum or
electrolytic capacitors at the point they enter the PC
board. For best performance, bypass all power sup-
plies to the appropriate ground with a 10F tantalum
