Probably this is the IF output. Simpler design, but impossible to find filters. You know you got the right L. Do not connect the other to the ground. Testing continuity revealed it comes from a 3.

I came up with an Arduino library for MxLT. The mixing result must be an IF at a common frequency, such as the The frequency step of the tuner is Take the IF from tuner, consider it as any RF signal and perform an extra conversion. Also Fi2 mxl500t7 be replaced. Therefore local oscillator L.

Second approach requires impossible to find components while the third is an option only nxl5007t tuner can output an IF closer to standard FM IF. It has a programmable IF output and it can receive anything from 44 to MHz. This should be built inside a can you know those RF can coils inside every radio.

Simpler design, but impossible to find filters. Probably this is the IF output. Another two tracks come out from MxLT and are capacitor coupled.

These seem to be software mxl007t, because the product brief sheet claims this IC can receive from 44 to MHz.

Although you pass frequency in Hz, it is rounded to multiples of Hz. First of all I had to trace some lines due to the lack of pinout information. Do not short them.

This is actually called double superheterodyne receiver. But, a closer look at the tuner which was basically an area of the PCB enclosed in metallic box revealed only a few tracks coming out of the tuner area.

Remember not to connect it to 5V Arduino without level shifter. Adjustment is done by setting the tuner to a frequency of a radio station and then tuning the coil until you receive it.

To see if I got the pinout right and test the reception I had to build a demodulator. The practical disadvantage of this double conversion is that you have to build and adjust the local oscillator LC pair. Post a Comment Please read the comments policy before publishing your comment.

Then I cut really the PCB and placed the tuner inside a metal box with easy linhx make connections.

I have no idea if this is an I-Q output or a simple differential output. Here you can use an LC pair tuned to After this frequency conversion, the resulting intermediate frequency signal is passed to a demodulator.

Whether or not you stumbled upon this IC in a receiver, it is good to know that sometimes you can work things out even without a datasheet. IF inversion does not affect the signal unless your detector is not centered on the right IF frequency. In the end, my tuner had fewer pins than the original one in the case.

There is no datasheet for it, but there are Linux drivers. Two other tracks are pulled up with 4. Probable pinout of MxLT tuner on PCB Linhx input and loop output were very easy to identify since the original antenna connectors were soldered into those places.
