charbel-j-estephan/Fm_Stereo_Encoder_Decoder
FM stereo encoder and decoder with 19 kHz pilot, designed in LTspice and KiCad.

The CD4013 is a flip Flop made by Slkor in a SOP-14 package with 14 pins. -40℃~+85℃ 1、1 2 24MHz 2ns 3V~15V 4uA 5pF 6.8mA 6.8mA 7ns 90ns@15V,50pF Asynchronous CD40 Complementary type D-Type Rising Edge Set and Reset SOP-14 Flip Flops ROHS.
PCBKit's library has its KiCad symbol (4xxx:4013, from KiCad's library) and its footprint (Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, from KiCad's library), ready for a KiCad board. 5,222 are in stock at JLCPCB (part C3041278). 4 open-source boards in 3 repositories on GitHub use it.
