Notes on Applications

1) Power supply

The CXA1550 series is designed to operate on either single or split power supply. The ripple rejection

performance is excellent for either supply. VCT (Pin 4) is a reference voltage of the VCC/2 buffer amplifier.

With single power supply operation, internally generated VCC/2 voltage appears at the pin, and a bypass

capacitor has to be connected between the pin and ground. On split power supply operation, the VCT (Pin

4) pin has to be connected to ground, and VEE (negative power supply) is supplied to the GND (Pin 15) pin.

2) Double speed (×2)

The CXA1550 series provides double speed encode/decode modes, which offer high speed dubbing

function. On double speed mode, the frequency response shifts twice as the normal B type.

3) Operational mode control

The CXA1550 series provides fully electronic switching circuits. The functions are controlled by DC voltage

of the two control pins of REC/PB (Pin 12) and ON/OFF/×2 (Pin 5). The switching truth tables are shown in

Table 1.

VCC ≥ V ≥ VCC–0.5 V

VCC–2.5 V ≥ V ≥ VEE+2.5 V

VEE+0.5 V ≥ V ≥ VEE

Pin 5 NR OFF

NR ON

Table 1.

It is desirable to provide CR time constant circuits at the mode control pins with time constant from 100

msec to 1 sec, which will reduce switching clicks effectively.

4) Reference levels

Characteristics and specifications of the Dolby noise reduction processor are defined as the levels and

measured with reference to the Dolby level. This particular level in these devices is –10 dBm (245 mVrms),

and is measured at the recording output (REC OUT) in the NR off mode.

The reference levels of the recording input (REC IN), playback input (PB IN) and line output (LINE OUT)

are defined as the levels which provide the Dolby level at the recording output in the NR off mode.

The CXA1550 series has a common silicon die, and has different internal connection (AL pattern). The

series provides four 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

Recording output level (=Dolby level)

Recording input level

–10 dBm (245 mVrms)

–30 dBm (24.5 mVrms)

0 dBm (775 mVrms)

–3 dBm (548 mVrms)

–6 dBm (388 mVrms)
