CXA2560Q
E97438A79-PS
Dolby
B Type Noise Reduction System with Playback Equalizer Amplifier
Description
The CXA2560Q is an IC designed for use in car
stereo cassette decks. Functions include Dolby B type
noise reduction (NR) system, playback equalizer
amplifier and music sensor into a single chip.
Features
Few external parts
Small package (40-pin QFP)
Same pin configuration as for the Dolby B-C type
NR system (CXA2561Q) and no Dolby NR system
(CXA2559Q)
Dolby B type NR and playback equalizer amplifier
into a single chip
FORWARD/REVERSE head select switch
Mute function
Music signal interval detection level can be set by
the external resistors/capacitors (2 modes).
High-frequency cut-off of the music sensor circuit
can be adjusted by the external capacitance.
Applications
Car stereo cassette decks
Playback-only cassette decks

2. Gain adjustment method
Adjust the playback equalizer amplifier gain so that 6dBm (Dolby level) is output on LINEOUT (Pins 7 and 24)
by playing back the reference tape for Dolby level adjustment.
Adjustment should be performed according to the rules of Dolby Laboratories Corporation because this IC has
the built-in Dolby NR system.
Dolby level is defined as 200nWb/m measured according to the ANSI high efficiency head method.

Fig. 3. Playback equalizer amplifier block diagram
The CXA2560Q 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 (70s/120s).
When TAPESW (Pin 18) is Low, Ri is 7k
; when TAPESW is High, Ri is 12k
.
The gain can be adjusted by connecting VR between PBOUT (Pins 2 and 9) and OUTREF (Pin 3 and 28); or
by using VR for the external R1.

(1) Adjustment of music signal 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/ (2
Cext Rext)
Cext, Rext: C3, R7 or C4, R8
(3) High-frequency cut-off adjustment of music sensor
Adjust 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/ (2
(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.

5. Operating mode control method
The CXA2560Q has a Dolby NR switch (NRSW), 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).

Notes on Operation
1. DIREF pin resistance
The current on DIREF (Pin 25) is the reference for the Dolby NR static characteristic, playback equalizer
amplifier resistor 7k
/12k
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. Dolby NR
The Dolby NR attack/recovery time is determined by the capacitance connected to TCH (Pins 8 and 23).
Use the parts, connected to these pins, with high accuracy and small temperature characteristics.
(The capacitance accuracy of 10% <film> is recommended.)
3. 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.
4. 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.
