... Extensive use of power and ground planes, ground plane fill in unused areas and surface mount decoupling capacitors are recommended. Decoupling capacitors should be as close to the pins of the CS4207 as pos- sible. The low value ceramic capacitor should be closest to the pin and should be mounted on the same side of the board as the CS4207 to minimize inductance effects ...

... QFN Thermal Pad The CS4207 is available in a compact QFN package. The underside of the QFN package reveals a large metal pad that serves as a thermal relief to provide for maximum heat dissipation. This pad must mate with an equally dimensioned copper pad on the PCB and must be electrically connected to ground. A series of vias should be used to connect this copper pad to one or more larger ground planes on other PCB layers ...
