Description
The CXA3556N is a one-chip integrated IC that processes IF signals of a digital broadcast tuner and includes an AGC amplifier circuit, a mixer circuit, a local oscillator circuit and an output amplifier circuit.
The package utilizes a 24-pin SSOP suitable for surface mounting.

Features
• AGC control width that has a 56dB variable range
• Low noise characteristics
• Low distortion characteristics (in particular, during AGC gain reduction)
• Includes switching function between down converter mode and linear amplifier mode
• Variable output amplifier gain by changing external resistance
• Includes RF AGC output pin
• Variable RF AGC settings
• AGC control curve characteristics with excellent linearity

Applications
    Digital broadcast tuners
