Circuit 2. Ear jack_3.5pi with MBHC
Note: Total capacitance on HPH_L/R and HS_MIC line SHOULD be under 1nF.

NOTE : If you have FM / DMB ANT issue,
headset and FM / DMB radio antenna.
please refer to ref schematic; 80-NK807.

Note : R6616 Pull-down resister is to prevent
malfunction when plugging aux accessory.

1. Using codec internal SW pull-down option
To improve crosstalk performance, you can make tank circuit. (L6601,L6606)
Make sure that you should add inductor which has under 0.3 ohm DCR,
and also care about total inductace for ANT performance.
