- Excellent spurious radiation by direct detection type
- Built-in muting function (retuned noise detection type)
- Built-in buffer amplifier for muting signal detection
- Built-in muting amplifier
- Built-in detector circuit
- Muting attenuation (VCC = 1.2V, Ta = 25°C) ATT = 65dB (typ.)
- Two built-in RF amplifiers
- Low supply current (VCC = 1.2V, Ta = 25°C) ICC = 4.0mA (typ.)
- Operating supply voltage range (Ta = 25°C) VCC (opr) = 0.95~2.2V
