Application Note

The CXA1560 series is a stereo Dolby B-C type NR IC like the CXA1330 series.

Built-in spectral skewing circuit allows smaller package.

1) Power Supply

The CXA1560 series is designed to operate on either single or dual power supply.

For dual power supply, connect VCT to GND, and VEE to the negative power supply.

For single power supply, connect V^EEto GND. Vcc/2, generated from the internal circuit, is output to VCT.

Connect a by-pass capacitor between this pin and GND.

The operating voltage range is ±3.5 to ±8.0V (7.0 to 16V), which satisfies the signal handling of 12dB

specified by the Dolby Laboratories.

2) Operation Mode Control

The CXA1560 series has built-in electronic switches. The operations are controlled by the DC voltages of

NRSW and MODE control pins. Table 1 shows the switching truth tables.

For single power supply, VH, VM, and VL correspond to Vcc, Vcc/2 and GND, respectively.

For dual power supply, VH, VM and VL correspond to Vcc, GND and V^EE, respectively.

Refer to “threshold” on the characteristics graph for the thresholds of the control voltages. NRSW and

MODE control pins are connected to VCT via a 50kΩ resistor, so when the pin is open, VM condition

results.

3) Reference level

The CXA1560 series Dolby level is –6dBm (388mVrms), and is measured at the recording output pin (REC

OUT) in the NR OFF mode. The reference level of the recording input pin (LINE IN), playback input pin (PB

IN) and line output pin (LINE OUT) are defined as the levels which provide Dolby level at the recording

output pin in NR OFF mode.

4) MPX Filter

The CXA1560 series provides an MPX (FM multiplex) filter ON/OFF function.

Connect the MPX filter between MPX IN and MPX OUT. In MPX ON mode, the line input signal is fed to the

NR processor via the MPX buffer amplifier and MPX filter. In MPX OFF mode, the signal bypasses the

buffer amplifier and filter, and is fed directly to the NR processor. The MPX buffer amplifier gain is 10dB.

The gain from LINE IN to LINE OUT is 19dB, and from MPX IN to LINE OUT it is 13dB, for a deviation of

6dB. This means that if a filter with insertion loss of 4dB is used, there is no fluctuation between MPX ON

and MPX OFF.
