General description
The CX24118A is a direct down-conversion satellite tuner intended for high-volume digital video, audio, and data receivers. The CX24118A offers excellent phase noise performance and very low implementation loss, required for advanced modulation systems such as 8PSK and DVB-S2.
The CX24118A has a built-in auto-tuning system that eliminates the need for software calibration. The on-chip fractional synthesizer enables fine frequency step size without adversely affecting lock time. The CX24118A does not require a balun, thus reducing external BOM cost. Its highly integrated design saves valuable board space and simplifies RF layout.
Features
- Single-chip RF-to-baseband satellite receiver
- Zero-IF architecture eliminates the need for image reject filtering
- Very low phase noise integrated Local Oscillators (LOs) for 8PSK and DVB-S2 applications
- Variable baseband filters for optimal interference rejection
- Auto-tuning system eliminates need for software calibration
- Very low power consumption
- Small (6 mm x 6 mm) footprint
- Lead-free package
