Description
The CXA1563M/S is a bipolar IC incorporating
dual channel Dolby B-C type noise reduction (NR)
system and Dolby S type switch. Dolby B-C-S type
stereo system is completed by using this IC in
conjunction with two CXA1417S or two CXA1417Q.
A reduction in the number of external parts and
small package have been achived due to the fact
that the spectral skewing circuits are all on-chip.

CXA1563M/S
Application Note
The CXA1563M/S is a dual channel Dolby B-C type NR IC with a built-in S type (CXA1417S/Q) switch. By
using the CXA1563M/S in conjunction with two sets of the CXA1417S/Q encoder unit, a stereo Dolby B-C-S
type NR system can be achieved.
1) Power Supply
The CXA1563M/S is designed to operate on either single or dual power supply.
For dual power supply, connect VCT (Pin 28) to GND, and V
EE
(Pin 14) to the negative power supply.
For single power supply, connect V
EE
(Pin 14) to GND. Vcc/2, generated from the internal circuit, is output to
VCT (Pin 28). 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) Supply Voltage of the CXA1417S/Q and the CXA1563M/S
(1) When both have split power supply
Set within the respective specified ranges.
CXA1417S/Q: AV
CXA1563M/S: BV
(2) When both have single power supply
Set at the same potential with the range specified for the CXA1417S/Q (9 to 13V).
CXA1417S/Q: AV
CXA1563M/S: BV
(3) Single and dual power supplies can not be used together.
3) Operation Mode Control
The CXA1563M/S has built-in electronic switches. The operations are controlled by the DC voltages of SSW
(Pin 12), NRSW (Pin 13) and MODE (Pin 16) 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 (Pin 13)
and MODE (Pin 16) control pins are connected to VCT via a 50k
resistor, so when the pin is open, VM
condition results. SSW (Pin 12) control pin is of PNP base input, so the pin can be used as VH when it is
open.
SSW is taken precedence over NRSW, and NRSW is invalid when SSW is at Low.

CXA1563M/S
4) Reference level
The CXA1563M/S 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.
5) MPX Filter
The CXA1563M/S provides an MPX (FM multiplex) filter ON/OFF function.
Connect the MPX filter between MPX IN (Pins 4 and 21) and MPX OUT (Pins 5 and 20). 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.
6) Notes on Operation
If the CXA1563M/S is used without being connected to the CXA1417S/Q encoder unit, SIN (Pins 8 and 21)
must be connected to GND for dual power supply, and to VCT for single power supply. There is a risk of
misoperation if the SIN pins are left open during use.
