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.

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 50kΩ 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 VM VL B-C type — S type NRSW C type B type NR OFF MODE MPX ON REC (Encode) MPX OFF REC (Encode) PB (Decode) SSW Table 1 SSW is taken precedence over NRSW, and NRSW is invalid when SSW is at Low. – 10 – 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. – 11 – CXA1563M/S Example of Representive Characteristics 15 Current consumption vs. Input level Encode Mode Single power supply 14 16 B type ICC — Current consumption [mA] ICC — Quiescent current consumption [mA] Quiescent current consumption vs. Supply voltage NR OFF 13 12 C type 11 10 15 Bf = 10k 14 Cf = 10k 13 12 NR OFF Bf = 1k 11 Cf = 1k 10 8 4 6 8 10 12 14 VCC — Supply voltage [V] 16 –12 B type encode characteristics 12 VCC = ±6V 0dB = Dolby Level –8 –4 0 4 Input level [dB] 8 12 C type encode characteristics 24 –40dB 10 VCC = ±6V 0dB = Dolby Level –60dB 20 –30dB 8 Encode boost [dB] Encode boost [dB] Encode Mode VCC = ±6V 0dB = Dolby Level 6 –50dB 16 –40dB 12 4 –20dB 2 –10dB 4 0 0dB 0 8 –30dB –20dB –10dB 0dB 100 200 500 1k 2k 5k Frequency [Hz] 10k 20k 100 200 16 NR OFF Maximum output level [dBm] Signal handling [dB] 20 C type 10 14 Encode Mode VCC = ±6V THD = 1% f = 1kHz NR OFF 12 10 8 6 4 0 4 10k 20k Load characteristics Signal handling Encode Mode f = 1kHz THD = 1% 0dB = Dolby Level 500 1k 2k 5k Frequency [Hz] LINE OUT 200 8 10 12 14 16 6 VCC – VEE — Supply voltage [V] – 12 – REC OUT 500 1k 2k 5k Load resistance [Ω] 10k CXA1563M/S NR OFF total harmonic distortion-2 NR OFF total harmonic distortion-1 Encode Mode f = 1kHz 0dB = Dolby Level Total harmonic distortion [%] Total harmonic distortion [%] Encode Mode VCC = ±6V 0dB = Dolby Level 0.1 f = 10kHz f = 100kHz f = 1kHz 0.01 –4 0 4 8 12 16 Output level [dB] 0.1 VCC = ±3.5V –4 20 0 4 8 12 16 Output level [dB] 20 B type total harmonic distortion-2 B type total harmonic distortion-1 Encode Mode f = 1kHz 0dB = Dolby Level Total harmonic distortion [%] Encode Mode VCC = ±6V 0dB = Dolby Level Total harmonic distortion [%] VCC = ±8.0V 0.01 0.1 f = 100Hz f = 1kHz 0.01 0.1 VCC = ±3.5V VCC = ±8.0V 0.01 f = 10kHz –4 0 4 8 12 16 Output level [dB] –4 20 C type total harmonic distortion-1 Encode Mode VCC = ±6V 0dB = Dolby Level 1.0 f = 10kHz 0.1 4 8 12 16 Output level [dB] 20 C type total harmonic distortion-2 Total harmonic distortion [%] Total harmonic distortion [%] 1.0 0 f = 100Hz Encode Mode f = 1kHz 0dB = Dolby Level VCC = ±3.5V 0.01 VCC = ±8.0V f = 1kHz 0.01 –4 0 4 8 12 16 Output level [dB] 20 –4 – 13 – 0 4 8 12 16 Output level [dB] 20 CXA1563M/S Cross talk Cross talk [dB] –50 VCC = ±6V Input = ±10dB Refer to Dolby Level NR OFF –60 –70 PB ch to ch REC ch to ch –80 VCC 14 VCN — NR control voltage [V] –40 NR control threshold –90 REC to PB –100 12 C type 10 VCC 2 B type 8 6 4 NR OFF 2 PB to REC 100 200 500 1k 2k Frequency [Hz] 5k 0 10k 4 MODE control threshold VCS — S type switch control voltage [V] VCM — MODE control voltage [V] 12 MPX ON 10 VCC 2 8 MPX OFF 6 4 PB 2 0 4 6 8 10 12 14 VCC — Supply voltage [V] 8 10 12 14 VCC — Supply voltage [V] 16 S-type switch control threshold VCC 14 6 12 10 – 14 – B-C type VCC 2 8 6 4 S type 2 0 16 VCC 14 4 6 8 10 12 14 VCC — Supply voltage [V] 16 CXA1563M/S Package Outline Unit: mm CXA1563M 28PIN SOP (PLASTIC) 375mil + 0.4 18.8 – 0.1 + 0.4 2.3 – 0.15 28 15 14 1 0.45 ± 0.1 0.5 ± 0.2 9.3 10.3 ± 0.4 + 0.3 7.6 – 0.1 0.15 + 0.2 0.1 – 0.05 + 0.1 0.2 – 0.05 1.27 ± 0.12 M PACKAGE STRUCTURE PACKAGE MATERIAL EPOXY / PHENOL RESIN SONY CODE SOP-28P-L04 LEAD TREATMENT SOLDER PLATING EIAJ CODE ∗SOP028-P-0375-D LEAD MATERIAL 42 ALLOY PACKAGE WEIGHT 0.7g JEDEC CODE CXA1563S + 0.1 05 0.25 – 0. 28PIN SDIP (PLASTIC) 400mil + 0.4 26.9 – 0.1 1 + 0.3 8.5 – 0.1 15 10.16 28 0° to 15° 14 0.5 ± 0.1 + 0.4 3.7 – 0.1 3.0 MIN 0.5 MIN 1.778 0.9 ± 0.15 PACKAGE STRUCTURE PACKAGE MATERIAL EPOXY RESIN SONY CODE SDIP-28P-01 LEAD TREATMENT SOLDER PLATING EIAJ CODE SDIP028-P-0400-A LEAD MATERIAL COPPER / 42 ALLOY PACKAGE WEIGHT 1.7g JEDEC CODE – 15 –
