• Manufacturer Part Number: TEA6825T
• Description: In Car Entertainment ICE car radio
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
Notes to the characteristics
1. For typical adjusting range see Figs 10 and 13.
2. For typical curve see Fig.11.
3. The static mute voltage follows the unweighted voltage level as function of FM-IF
4. The mono/stereo blend voltage is generated as a function of FM-IF
5. The high-cut control voltage is generated as a function of FM-IF
6. f
7. The AM oscillator signal is generated by division of the 61.5 MHz crystal oscillator. Two divider ratios programmable
8. For typical AM level curve see Fig.15.
9. For AM detector; f
