CXA3555N

All Band Tuner IC with On-chip PLL

Description

The CXA3555N 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 (3 sets) 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: 5mA)

• 30-pin SSOP small package

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.
