SL5019

The SL5019 is designed as one kind of low power narrow band FM IF. It performs single conversion FM reception and consist of oscillator, mixer, limiting IF amplifier, and meter drive circuitry. This device is designed for use in FM dual conversion communication equipment. It is similar to the SL5018 FM IFs, except that a signal strength indicator replaces the scan function controlling driver which is in the SL5018. It is design for the use of parallel LC components. This device also requires fewer external parts than earlier products. It is available in dual-in-line and surface mount packaging.

The features of the SL5019. (1)Wide operating supply voltage range: Vcc=2.0 to 9.0V. (2)Input limiting voltage sensitivity of -3.0dB (2uV). (3)Low drain current: Icc=3.2mA, (Vcc=4.0V, squelch off). (4)Minimal drain current increase when squelched. (5)Signal strength indicator: 60dB dynamic range. (6)Mixer operation frequency up to 100MHz. (7)Fewer external parts required than earlier devices. Those are all the main features.

Some absolute maximum ratings of the SL5019 have been concluded into several points as follow. (1)Its maxium supply voltage would be 10V. (2)Its supply voltage would be 2.0V to 9.0V. (3)Its detector input voltage would be 1.0V. (4)Its RF input voltage would be 1.0Vrms. (5)Squelch input voltage would be 6.0V. (6)Its mute function would be from -0.7V to +10V. (7)Its mute sink current would be 50mA. (8)Its operating temperatur range would be from -20°C to 70°C. (9)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of the SL5019 are concluded as follow. (1)Its detector output DC voltage would be min 0.9V and typ 1.6V and max 2.3V. (2)Its filter output DC voltage would be min 1.5V and typ 2.5V and max 3.5V. (3)Its trigger hysteresis would be min 34mV and typ 57mV and max 80mV. And so on.
