i dont known to use PIN of TP3067, help me pls,
my project : i want converte analog to PCM, i have syn..clock 8kHz,bit clock 256kHz, and clock 2,048MHZ,
im want use PIn 17,18,19
i want converte analog signal to pcm, can u help a circuit
send a diagram (circuit) for me pls

Use circuit in figure 1 of the datasheet. First of all you need to determine the levels that you need for the conversion. Depending of the gain of your analog interface (between the analog line and the codec) you must calculate the maximum expected level at the codec input and the maximum needed signal at the codec output. From the datasheet you can see that this codec is equiped with two opamps one for setting input (transmit) gain and one for setting output (receive) gain. Input is "ANALOG IN" and output "VPO-". There is a third opamp for driving balanced loads if you dont need it leave "VPO+" opened. In the datasheet you can see that 0 dbm0 (~3dB less than digital clipping voltage) is 1.2276Vrms. If you cannot calculate the exact gains that you need experiment starting with 10K resistors for all R1,R2,R3,R4 resistors.The pinout depending on the IC package that you use is on page 2.
You will be using long frame sync since you will connect your 8KHz signal to both FSR and FSX. Connect BCLKR and BCLKX to 256KHz and MCLKR and MCLKX to 2048KHz.
Do you need more help on your analog interface?
ty for ur reply, im trying to do that !
can u design for me an example for telefone, i want connect to ANALOGIn signal analog from telefone and i need signal PCM on Dx,
in other application i want connectto Dr (on other IC) PCM from Dx in this IC and converte PCM signal to analog signal?
can u help me and reply me by email pls, because i havenot enough point to doawloat file in this website.
