SA2104CS Datasheet | Silan Microelectronics

DESCRIPTION The SA2104C/SA2104CS are single-chip tuner ICs that incorporate FM/AM and MPX circuits, which are designed for portable radios and 3V headphone radios. The SA2104C/SA2104CS are suitable for digital tuning system applications. FM local oscillation voltage is set up low relativity, for NEW FCC. S D IP -24-300-1.778 FEATURES - Operating supply voltage range: VCC=1.8~10V (Tamb=25°C) - For NEW FCC - FM/AM and MPX integrated in a single-chip. - Build in FM/AM IF count buffer. FM: 1.3375MHz (1/8 dividing) AM: 450k Hz - Build in mute circuit for IF count output according to field strength. - Build in FM MPX VCO circuit - Build in FM/AM OSC buffer output for DTS applications. - Build in AM low cut circuit - Build in stereo indicator. - Low supply current. (VCC=3V, Tamb=25°C) ICCq (FM)=11.0m A (Typ.) ICCq (AM)=7.5m A (Typ.)
