Notes on Applications

1) Power supply

The CXA1100 Series is basically designed to operate on single ended supply. The split supply operation isalso possible, however, VEE(negative) supply should provide low noise and ripple characteristics. Theripple rejection ratio of these devices is generally good for Vcc supply (single ended supply and splitsupply), however, that for VEEsupply is not so good in the NR on mode because the integrated capacitorsfor the side chain filter are connected to pin 15 (VEEon split supply).

The devices will satisfy the signal handling of 12dB specified by Dolby Laboratories on above voltage range.2) Operation mode control

The CXA1100 series provide fully electronic switching circuits. The functions are controlled by DC voltagesof the two control pins of REC/PB (pin 12) and ON/OFF (pin 5). The switching truth tables are shown in Fig. a-2. VHand VLare defined as

It is desirable to provide CR time constant circuits at the mode control pins with time constant from100msec to 1sec, which will reduce switching clicks effectively.

3) Reference levels

Characteristics and specifications of the Dolby noise reduction processor are defined as the levels andmeasured with reference to the Dolby level. This particular level in these devices is –10dBm (245mVrms),and is measured at the recording output (REC OUT) in the NR off mode.

The reference levels of the recording input (REC IN), play back input (PB IN) and line output (LINE OUT)are defined the levels which provide the Dolby level at the recording output in the NR off mode.

The CXA1100 series has a common silicon die, and has different internal connection. The series providesfour different line output levels for various applications. Other reference levels, recording input level,playback input level and recording output level (= Dolby level) are identical in all devices.The reference levels are as follows

4) MPX filter termination and C1for Vcc/2 (Pin 4)

The MPX (multiplex) filter termination method shown in Fig. a-3 allows saving the coupling capacitorsbetween the buffer amplifiers and MPX filters. However, the channel to channel separation and REC to PBcrosstalk of low frequency signals will be degraded by the termination resistor RT. For example, 5kΩof R1will degrade the channel to channel separation to 50dB. Better separation can be obtained by increasingthe capacitance of C1(Pin 4) to 220µF or 470µF.

The allowable minimum value of C1is 47µF, and 100µF is the standard recommended value. Larger valuesof C1are generally desirable in order to improve the crosstalk and ripple rejection ratio.5) Application for dubbing cassette decks

The CXA1100 series generates non decoded signal at the recoding output in the decode mode, and cansimplify the structure of dubbing decks. See the SONY' Dolby B/C type IC (CX20187/CXA1097Q orCX20188/CXA1098Q) data sheet in detail.
