CXA3627ER
32 pin VQFN (Plastic)
Description
The CXA3627ER is a monolithic TV tuner IC which
integrates local oscillator and mixer circuits for VHF
band, local oscillator and mixer circuits for UHF
band, an IF amplifier and a tuning PLL onto a single
chip, enabling further miniaturization of the tuner by
adopting a small package.
Features
Low power consumption (5V, 63mA typ.)
Low noise figure, low distortion characteristics
High gain/low gain selectable
Supports IF double-tuned/adjacent channel trap
Balanced oscillator circuits with excellent oscillation
stability
On-chip PLL supports I
2
C bus
On-chip high voltage drive transistor for charge
pump
Frequency step selectable from 31.25, 50 or
62.5kHz (when using a 4MHz crystal)
Low-phase noise synthesizer
On-chip 4-output band switch (output voltage: 5V,
current capacity: 13mA)
32-pin VQFN small package
UHF band switch output switchable
Applications
TV tuners
VCR tuners

Note:
This IC has pins whose electrostatic discharge strength is weak as the operating frequency is high
and the high-frequency process is used for this IC. Take care of handling the IC.
