Sets the value for the L counter. 000100000000 = 256 fractional clock divider,
100000000000 = 2048 fractional clock divider.
Sets the value for the M counter. 011000011011 = 1563 fractional clock divider,
100000000 = 2048 fractional clock divider.
Fractional clock divider. Set 1 to select the ADC clock to come from the fractional clock
divider, or 0 to bypass the ADC clock from the fractional clock divider.
ADC clock selection. Set 0 to select the ADC and fractional divider clocks to come from
the reference divider/multiplier.

Applications Information
The LNA and mixer inputs require careful consideration
in matching to 50 I lines. Proper supply bypassing,
grounding, and layout are required for reliable perfor-
mance from any RF circuit.
Layout Issues
The MAX2769B EV kit can be used as a starting point
for layout. For best performance, take into consideration
grounding and routing of RF, baseband, and power-
supply PCB proper line. Make connections from vias
to the ground plane as short as possible. On the high-
impedance ports, keep traces short to minimize shunt
capacitance. EV kit Gerber files can be requested at
www.maximintegrated.com .
Maxim Integrated
Power-Supply Layout
To minimize coupling between different sections of the
IC, a star power-supply routing configuration with a large
decoupling capacitor at a central V CC_ node is recom-
mended. The V CC_ traces branch out from this node,
each going to a separate V CC_ node in the circuit. Place
a bypass capacitor as close as possible to each supply
pin This arrangement provides local decoupling at each
V CC_ pin. Use at least one via per bypass capacitor for
a low-inductance ground connection. Do not share the
capacitor ground vias with any other branch.
