Adopting a static method for the input/output part,

We are planning to simplify the improvement design.

Due to differences in display methods.

The PLL circuit and the control circuit are integrated into one chip.

It can correspond to each region of Japan, the United States, and Europe, and has three bands of PM/MW/LW in the European region. in the Japan-U.S. region

Built-in preset memory of 16 stations, various application methods are possible. Also, the last of each band

It also has number memory and last channel memory.

TC9146AP has 6 stations each for PM/AM (MW + LW) preset memory.

The auto stop circuit has been enhanced, and sufficient consideration has been given to the stop during auto search operation.

It has a built-in LED driver for display, and almost no external components are required.

For PM, combine with the prescaler TD6104P to form a swallow counter and set the reference frequency to

The improvement of the performance is measured as 25kHz.

All of the various operation displays are static.
