1 / 34 page June 2007 Rev 2 1/34 1 TDA7417 Car radio audio processor Features ■ Input Multiplexer – QD: quasi-differential stereo inputs – FD: full-differential stereo inputs – Mono: Mono input – SE1: stereo single-ended input – SE2: stereo single-ended input – In-Gain 0 to 15dB, 1dB step – internal offset-cancellation (AutoZero) ■ IN/OUT control – Selectable full-differential stereo inputs or Bass output ■ Loudness –2nd order frequency response – programmable center frequency (400Hz/800Hz/2400Hz) – 15dB with 1dB steps – soft-step control with programmable blend times – selectable low & high frequency boost ■ Volume – +15dB to -79dB with 1dB step resolution – soft-step control with programmable blend times – multi-step control ■ Bass –2nd order frequency response – center frequency programmable in 4 steps (60Hz/80Hz/100Hz/200Hz) – Q programmable 1.0/1.25/1.5/2.0 – DC gain programmable – -15 to 15dB with 1dB resolution – soft-step control with programmable blend times ■ Treble – 2nd order frequency response – center frequency programmable in 4 steps (10KHz/12.5KHz/15KHz/17.5KHz) – -15 to 15dB with 1dB resolution ■ High pass – 2nd order frequency response – center frequency programmable in 3 steps (80Hz/120Hz/160Hz) ■ Speaker – independent soft step speaker controls, +15dB to -79dB with 1dB steps – Independent programmable mix input with 50% mixing ratio for front speakers –direct mute – multi-step control ■ Mute Functions – digitally controlled SoftMute with 3 programmable mute-times (0.48ms/0.96ms/123ms) Description The TDA7417 is an high performance signal processor specifically designed for car radio applications with fully integrated audio filters. The digital control allows a full programming of the audioprocessor in a wide range of filter characteristics. By using BICMOS-process low distortion and low noise are obtained. TQFP32 Table 1.
