Features
• External parts greatly reduced with a built-in active filter.
• Count down can be used for broadcast mode discrimination so that adjustment for discrimination system (Q-OSC) is not required.
• Output level of 380 mVrms (1 kHz, MONO, 100 %)
• Forced monaural operates with both stereo and bilingual broadcasts.
• Built-in digital facsimile interference elimination filter.
• Low supply voltage (VCC=5 V)
• The pin configuration of the CXA1518S is identical to that of the CXA1138AS.
