Playback equalizer amplifier block diagram The CXA2559Q configures the playback equalizer amplifier by connecting the external capacitor C1 and resistor R1 shown in Fig. 3. Two systems (FORWARD and REVERSE) of playback head input are provided for each channel. The FORWARD input pin is selected when DRSW (Pin 19) is Low; REVERSE is selected when DRSW is High. The playback equalizer amplifier frequency response can be set in two levels (70µs/120µs). When TAPESW (Pin 18) is Low, Ri is 7kΩ; when TAPESW is High, Ri is 12kΩ. The gain can be adjusted by connecting VR between PBOUT (Pins 2 and 9) and OUTREF (Pins 3 and 28); or by using VR for the external R1.

Music sensor block diagram (1) Adjustment of music signal interval detection level Adjust the external resistors R7 and R8 to adjust the music signal interval detection level. The signal detection level v1 and no signal detection level v2 are expressed by the following equations. v1 = –39 + 20 log (39k/Rext) [dBm] Rext: R7 or R8 v2 = v1 – 2 [dBm] (2) Low-frequency cut-off adjustment of music sensor Adjust the external resistors R7, R8 and the external capacitors C3, C4 to adjust the low-frequency cut-off. The low-frequency cut-off is expressed by the following equation. fc1 = 1/ (2π · Cext · Rext) Cext, Rext: C3, R7 or C4, R8 (3) High-frequency cut-off adjustment of music sensor Connect the external capacitor C2 to MSLPF (Pin 10) to adjust the high-frequency cut-off. The high-frequency cut-off is expressed by the following equation. fc2 = 1/ (2π · (64p + C2) · 100k) The high-frequency cut-off is approximately 25kHz when MSLPF is left open . (4) Response time adjustment Adjust the external resistor R9 and the external capacitor C5 to adjust the response time. The response time for signal detection depends on the internal resistor R6 and the external capacitor C5. The response time for no signal detection depends on the external resistor R9 and the external capacitor C5. – 14 – CXA2559Q 5. Operation mode control method The CXA2559Q has a mute switch (MUTESW), playback equalizer amplifier select switch (TAPESW), head input select switch (DRSW), music sensor mode select switch (MSMODE) and music sensor switch (MSSW). The operation modes for each switch are shown in the following table.

DIREF pin resistance The current on DIREF (Pin 25) is the reference for the playback equalizer amplifier resistor 7kΩ/12kΩ and the comparator threshold value of the music sensor. Use the resistor with high accuracy for connecting to the DIREF pin. (The resistance accuracy of 2% <metal-oxide> is recommended.) 2. Playback equalizer amplifier The playback equalizer amplifier characteristics are determined by the resistor connected between the IC internal resistor and PBFB (Pins 31 and 40) and the capacitor connected between PBFB and PBTC (Pins 1 and 30). Use the parts which satisfies the accuracy required for the playback equalizer amplifier. 3. Music sensor The resistance and capacitance connected to G2FB (Pin 11) and G1FB (Pin 12) determine the detection level and high-frequency cut-off. The response time is determined by the resistance and capacitance connected to MSTC (Pin 13). Use the parts which satisfies the accuracy required for the music sensor. – 15 – CXA2559Q Example of Representative Characteristics Current consumption vs. Supply voltage 9.0 Ta = 25°C Current consumption [mA] 8.8 8.6 8.4 8.2 No signal MUTE OFF 70µs MS ON 8.0 7.9 5.0 6.0 7.0 9.0 8.0 10.0 11.0 12.0 Supply voltage [V] Playback equalizer amplifier frequency response 65 Ta = 25°C 60 PBFIN Gain [dB] 55 47µ 50 680 45 40 35 7k/12k VCC = 8.0V Input : PBFIN1 Output : PBOUT1 PBFB PBREF 120µs 70µs 30 25 270 1k 100 Gain [dB] 25 20 15 10 5 100 1k 2.2µ 0.01µ Fig. 6.
