CXA2513M
3-Band Preset Graphic Equalizer IC (with standby and memory on last preset mode)
Description
The CXA2513M is a 3-band preset graphic equalizer
developed for stereo set, cassette tape recorder with
radio, etc. It has 5 modes: FLAT, ROCK, VOCAL,
POP and JAZZ. The selection is via 5 control pins.
The center frequencies of three bands are 100Hz,
1kHz and 10kHz. The center frequencies of these
bands are determined by 2 external resistors. It also
has a standby feature. When the standby pin goes
low, the IC stores the last preset mode. When this
pin goes high, the IC restores the last preset mode
before standby. It can be initialized to any one of the
two preset modes (FLAT, ROCK) upon power up.
Features
• Very few external parts
• 3-band monolithic filters (100Hz, 1kHz, 10kHz)
• The center frequencies of the band-pass filters can
be adjusted
• 5 preset modes (FLAT, ROCK, VOCAL, POP, JAZZ)
• Equips with output ports to drive external LEDs
• Mute pulse output pin
• Standby feature with last preset mode memory
• Can be initialized to one of the two preset modes
(FLAT or ROCK)

Fig. 1 indicates the conventional graphic equalizer system. This circuit performs boost and cut-off near "fO"
controlled by the potentiometer Rv. ("fO" is resonance frequency determined by Z (s) (formed LCR).) The
operation can be seen as follows: When the LCR circuit goes to the far left of Rv, a state of graphic equalizer
becomes maximum cut-off. At that time, assuming transmittance as T (s), the following expression can be
obtained.

The structure of the graphic equalizer used in this IC is shown on Fig. 3. This circuit performs boost and cut-off
controlled by 2 transconductance amplifiers that can vary the conversion coefficient through control currents Ib,
and Ic around ωo. ("ωo" is center frequency determined by band-pass filter.) Output impedance Z (s) of Gm1,
Gm2 can be expressed as

The formula shows that this system and the aforementioned LCR circuit have equivalent impedance
characteristics on Z (s).
Then, regarding Gm as the maximum value of Gm1 and Gm2, the operation can be observed as follows.
Maximum cut-off occurs when Gm1 = Gm and Gm2 = 0. At that time transmittance T (s) is expressed as

This is equal to the frequency response of the conventional graphic equalizer at cut-off.
Also, maximum boost occurs when Gm1 = 0 and Gm2 = Gm. At that time transmittance T (s) is given by as

This is equal to the frequency response of the conventional graphic equalizer at boost.
As far as the operation is concerned the graphic equalizer on this IC and the conventional graphic equalizer
are equal, even when the system differs. The merit in using this IC's system rests with the fact that monolithic
filter technology realizes a graphic equalizer without external parts.
The structure of the actual graphic equalizer, including BPF, is shown on Fig. 4.

2. Power Up
There are two ways of powering up the CXA2513M. They are
1) VCC pin (Pin 15) goes high, and after some time, the STANDBY pin (Pin 16) goes high.
2) VCC pin and STANDBY pins both goes high together.
The two ways of power-up will results in different timing diagram and different initial mode.
If both VCC and STANDBY pins go high together, the REF capacitor (Pin 9) will charge to half VCC. The IC will
be initialized to ROCK mode. The timing diagram is shown in Fig. 5.

If the VCC pin goes high while the STANDBY pin is not connected to VCC, the IC is in standby condition. The
REF capacitor (Pin 9) and timing capacitor (Pin 5) will charge to VCC. Now, if the STANDBY pin is switched to
VCC, the REF capacitor will discharge to half VCC and the timing capacitor will discharge to a clamped voltage
(VCC – 5∗VBE).
During the discharging of timing capacitor, all the LEDs light up. When the timing capacitor voltage reaches a
certain threshold voltage, only the ROCK LED or FLAT LED lights up depending on Pin 4. If the Pin 4 is
connected to a capacitor, the IC is initialized to FLAT mode. If the Pin 4 is not connected, the IC is initialized to
ROCK mode. The timing diagram is shown in Fig. 6.

3. Mute Pulse Generation
The CXA2513M has one voltage comparator built-in. The built-in voltage comparator is used to produce mute
pulse during the depress of the preset mode switches. During depress the switch, there is a voltage pulse of
about 1V depending appearing at the cathode of the LEDs.
The mute detector comparator is used to detect this voltage changes at the cathode of LEDs and produce
mute pulse at Pin 12. The polarity of the mute pulse can be set. When the M_DET+ pin (Pin 18) is higher than
the M_DET– pin (Pin 17), the MUTE pin (Pin 12) will be high. When the M_DET+ pin (Pin 18) is lower than the
M_DET– pin (Pin 17), the MUTE pin (Pin 12) becomes low.
A capacitor is used to store the initial voltage before the depression of the mode switch. Once the switch is
depressed, the capacitor starts discharge. The values of the resistors and capacitor set the duration of the
mute pulse.
Notes on Operation
1) Value of Timing Capacitor
The timing and the duration of the MUTE pin and the LEDs light-up depends on the value of the timing
capacitor as the timing capacitor is discharging to (VCC – 5∗VBE).
The charging time constant is 250K∗(timing capacitor) and the discharging time constant is 150K∗(timing capacitor).
The two threshold values:
a) Latch Output Enable (LATCH_OE_ctl)
b) Latch enable/Mute disable (LATCH_ctl)
The threshold values of the Latch Output Enable (LATCH_OE_ctl) is set to (VCC – 3∗VBE) and the threshold
values of the Latch enable/Mute disable (LATCH_ctl) is set to (VCC – 4∗VBE).
So, the duration for all the LEDs light-up is
2∗VBE = (5VBE) exp (–t1/RC)
where R = 150K
and the sound appears after t2 seconds if the mute pulse output pin is used. This t2 is given by
VBE = (5VBE) exp (–t2/RC)
where R = 150K
Therefore, depending on the requirements of the time on the mute sound and the duration of all LEDs light-up,
choose the value of the timing capacitors.

2) Initialize Preset IC
The preset IC can be initialized into any one of the two modes out of the total 5 mods. The two modes are:
a) FLAT
b) ROCK
In order to initialize the preset IC into FLAT, one external capacitor (220nF) is required. While to initialize the
preset IC to ROCK, no external capacitor is required.
3) Supply voltage Ripple Rejection
The value of the REF capacitor (Pin 9) determines the supply voltage ripple rejection ratio (SVRR). A reduce in
this capacitance value decreases on the supply voltage ripple rejection ratio (SVRR).
4) Center Frequency of Band-pass Filters
The center frequency of the graphic equalizer is determined by an external resistor. This resistor is 160kΩ
external resistor connected to the ISET pin (Pin 8). It is recommended to use a resistor with the small
dispersion and temperature coefficients.
By varying the value of the resistor connected to the ISET pin, the frequency response of the graphic equalizer
can be shifted. By reducing the resistor value, all the three band-pass filters shift to high band. By increasing
the resistor value, the filters shift to lower band.
The center frequency of the bass band-pass filter can be varied independently. This bass center frequency is
determined by the external resistor (33kΩ) connected to the LOW-FREQ pin (Pin 13). By reducing the value of
this resistor, the bass center frequency shifts to higher frequency. By this value, the bass center frequency
shifts to lower frequency.
