com UTC TA7342P LINEAR INTEGRATED CIRCUIT PLL FM STEREO MULTIPLEX DESCRIPTION The UTC TA7342P is a PLL FM stereo multiplex integrated circuit, designed for portable radio applications.
FEATURES *Wide operating supply voltage : Vcc=1.
8V-5V *Suitable for LED driving : Ilamp=8mA(max.
) *VCO stop capability (The VCO is stopped when the LPF2 termianl is connected to the power supply line, and the the stereo indicator is turn off.
) *Easy Adjustment (The monitored free running frequency of VCO is 76kHz at stereo Lamp terminal SIP-9 BLOCK DIAGRAM UTC UNISONIC TECHNOLOGIES CO.
