CXA3627N
All Band Tuner IC with On-chip PLL
Description
The CXA3627N 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.
30 pin SSOP (Plastic)
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 I2C 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)
• 30-pin SSOP small package
• UHF band switch output switchable

Structure
Bipolar silicon monolithic IC
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.
