MC3371P

The MC3371P is designed as one kind of FM dual conversion communication equipment whcih perform single conversion FM reception and consist of an oscillator, mixer, limiting IF amplifier, quadrature discriminator, active filter, squelch switch, and meter drive circuitry.It is similar to the MC3361/MC3357 FM IFs, except that a signal strength indicator replaces the scan function controlling driver which is in the MC3361/MC3357 and for the use of parallel LC components, while the MC3372 is designed for use with either a 455 kHz ceramic discriminator, or parallel LC components.

Features of the MC3371P are:(1)input limiting voltage sensitivity of 3.0 dB;(2)wide operating supply voltage range:VCC=2.0 to 9.0 V;(3)low drain current: Icc=3.2 mA,@ VCC =4.0 V,squelch off;(4)minimal drain current increase when squelched;(5)signal strength indicator:60 dB dynamic range;(6)mixer operating frequency up to 100 MHz;(7)fewer external parts required than earlier devices.

The absolute maximum ratings of the MC3371P can be summarized as:(1)power supply voltage:10 Vdc;(2)RF input voltage (VCC>/=4.0 Vdc):1.0 Vrms;(3)detector input voltage:1.0 Vpp;(4)squelch input voltage:6.0 Vdc;(5)mute function:-0.7 to 10 Vpk;(6)mute sink current:50 mA;(7)junction temperature:150 °C;(8)storage temperature range:-65 to +150 °C.If you want to know more information such as the electrical characteristics about the MC3371P,please download the datasheet in www.seekic.com or www.chinaicmart.com .
