This application guide introduces the wide portfolio of advanced solutions that NXP offers for set-top-boxes (STBs). All these solutions are built on our deep understanding of what network operators and manufacturers need.
The guide provides an overview of NXP’s semiconductor solutions for set‑top boxes, covering power management, RF front‑end, audio/video conversion, HDMI connectivity, smart‑card readers, and high‑speed data interfaces. It is intended for designers who need reference architectures and component recommendations to build efficient, cost‑effective STB designs.
Key sections include AC/DC controller families (GreenChip, STARplug), silicon tuners and LNAs, audio DAC families, analog video switches, HDMI transmitters and switches, smart‑card interfaces, USB/USB 3.0/Ethernet/SD‑card protection, and a range of discrete components for the main processing board. Additional resources and web links are provided at the end of the document.
| TEA1520T/N2 standby supply | 48 V input, 2‑5 W output |
|---|---|
| BF1108 / BF1118 operating voltage | BF1108 5 V, BF1118 3.3 V |
NXP recommends the STARplug family of SMPS ICs for low‑power STBs, such as the TEA1520P/N2 part.
The guide includes HDMI transmitters, HDMI switches, CEC controllers, DDC and CEC buffers, and ESD protection for HDMI interfaces.
The BGU703x series LNA (e.g., BGU7031, BGU7032) is recommended for applications requiring better noise figure than integrated tuners.
NXP provides the UDA133x series (I²S interface) and the UDA1352TS / UDA1355 families for more complex audio I/O schemes.
