CXA1563M/S
Dolby B-C Type Noise Reduction System with Built-in S type Switch
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. Features * Few external parts * Spectral skewing circuit are on-chip * NR ON/OFF, REC/PB, MPX filter ON/OFF, Dolby S type switches * Small package (28-pin SOP, 28-pin SDIP) * Low current consumption 13mA Typ. (power supply 6V) * Dual channel processors Structure Bipolar silicon monolithic IC Absolute Maximum Ratings * Supply voltage * Operating temperature * Storage temperature * Allowable power dissipation CXA1563M 28 pin SOP (Plastic) CXA1563S 28 pin SDIP (Plastic)

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 VEE (Pin 14) to the negative power supply. For single power supply, connect VEE (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 VEE, 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. VH SSW NRSW MODE B-C type C type MPX ON REC (Encode) VM -- B type MPX OFF REC (Encode) Table 1 SSW is taken precedence over NRSW, and NRSW is invalid when SSW is at Low. VL S type NR OFF PB (Decode)

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.
