LC7215, 7215F, 7215FM
MW/LW PLL Frequency Synthesizers
Overview
The LC7215, LC7215F and LC7215FM are phase-locked-loop
frequency synthesizer LSIs that provide accurate reference
frequencies over the MW and LW bands, making them ideally
suited for AM tuners.
Package Dimensions
unit : mm
3003A-DIP14
[LC7215, 7215F]
Features
. PLL frequency synthesizer LSIs for MW and LW bands.
. Reference frequencies of 1, 5, 9 and 10 kHz.
. On-chip transistor for the low-pass filter amplifier.
. Single output pin (CMOS output)
. Controller clock output pin.
. Time-base output pin.
. All devices can be used for double conversion demodulation.
. The LC7215F and 7215FM have expanded input frequency
ranges.
