| Semiconductor SL5019/P LOW POWER NARROW BAND FM IF Description The SL5019/P performs single conversion FM reception and consist of oscillator, mixer, limiting IF amplifier, and meter drive circuitry. These devices are designed for use in FM dual conversion communication equipment. The SL5019/P is similar to the SL5018 FM IFs, except that a signal strength indicator replaces the scan function controlling driver which is in the SL5018. The SL5019/P is design for the use of parallel LC components. This device also requires fewer external parts than earlier products. The SL5019/P are available in dual-in-line and surface mount packaging. Features * Wide operating Supply Voltage Range : VC C = 2.0 to 9.0V * Input Limiting Voltage Sensitivity of -3.0 dB (2 A) * Low Drain Current : Icc=3.2mA, (VC C =4.0V, Squelch off) * Minimal Drain Current increase When Squelched * Signal Strength indicator : 60dB Dynamic Range * Mixer operation Frequency Up to 100MHz * Fewer External Parts Required than Earlier Devices.
