I built a project in school to decode and re-generate MTS stereo from a composite audio input, using my Sony 7" TV-720 to demonstrate.
It was easier to adapt an NTE-743, which is a similar IC to the MC1310, a Motorola chip.

As I fuzzily recall 30 years later, the range of the pilot tone generator on the NTE (an LM-something) could be tuned to 15.7 kHz. But the Motorola IC was designed to be stable at 19 kHz and varying it did not work well.
