NXP digital satellite tuner
IC CX24113A
Highly integrated, worldwide satellite
silicon tuner
The CX24113A is NXP’s third generation direct down-conversion satellite tuner RF IC intended for
operator-based digital satellite networks and free-to-air systems.
Key features
Ñ Single-chip RF-to-baseband satellite receiver
Ñ Zero-IF architecture eliminates the need for image reject
filtering
Ñ Variable baseband filters for optimal interference rejection
Ñ Auto-tuning machine eliminates the need for software
calibration
Ñ Very low power consumption
Ñ Small (6 mm x 6 mm) footprint
Ñ Lead-free package
Applications
Ñ DSS/DVB set-top boxes
Ñ Digital VCR (DVR)
Ñ Commercial digital video, audio, and data receivers
The CX24113A is a highly integrated satellite tuner solution
that incorporates an advanced Fractional-N synthesizer, I²C
serial interface, a fully integrated local oscillator, and variable
baseband filters. The device has an improved power supply
rejection ratio (PSRR), requires a single +3.3V supply, and
features very low power consumption.
The CX24113A has a built-in auto-tuning machine that
eliminates the need for software calibration and accelerates
the calibration time. The on-chip fractional synthesizer enables
fine frequency step size without adversely affecting lock time.
The CX24113 does not require a balun, thus reducing external
bill of materials (BOM) cost. Its highly integrated design saves
valuable board space and simplifies RF layout.
