PC3202GR
FREQUENCY DOWN CONVERTER FOR
VHF to UHF BAND TV/VCR TUNER
DESCRIPTION
The
µ
PC3202GR is Silicon monolithic IC designed for TV/VCR tuner applications. This IC consists of a double
balanced mixer (DBM), local oscillator, preamplifier for precscaler operation, IF amplifier, regulator, and so on. This
one-chip IC covers a wide frequency band from VHF to UHF bands. This IC is packaged in 20-pin SSOP (Shrink
Small Outline Package) suitable for surface mounting.
