Application Note
1.
Power Supply Line
This IC has two voltage supply pins, VCC (for stages of AM, FM IF and MPX) and RF VCC (for FM RF
stage). Please keep the potential difference between these power supply pins at 0.4 V (typ.) or less.
Otherwise, it may cause the IC to malfunction.
Also, please keep the potential difference between the VCC (tuner power supply) and the VDD (PLL power
supply) at 1 V or less. Otherwise, due to improper interaction between analog and digital blocks, a
malfunction may occur.
2.
Crystal Oscillator External Constant
When the constants of external components C1 and C2 are determined, please show the IC with the final
layout of the board to a crystal oscillator manufacturer and test it to confirm the constants.
If you need an IC to adjust parameter values to compensate for variables in layout, ask Toshiba.
Please use a crystal oscillator with lower CI value
Toshiba tested a crystal oscillator from DAISHINKU CORP. (CI value is 30 k max) using a Toshiba
evaluation board.
