SI2166-D60-GMR

SI2166-D60-GMR is Silicon Labs’ RF front-end/tuner IC intended for digital TV receivers. It provides broadband RF input with an integrated front-end (LNA, mixer) and a programmable intermediate-frequency/synthesizer, controlled over I2C, and designed to work with a separate digital demodulator/SoC. The “D60” denotes the 60‑pin (QFN) package, and “GMR” is the package/variant code. It covers the RF bands used for terrestrial and cable TV and is configured to support common standards (e.g., DVB-T/T2/C) via register settings and external RF components per the reference design. Typical applications include set-top boxes, DVB receivers, USB tuners, and other multiband RF front-ends where integration reduces BOM and board size. For exact pinout, electrical specs, register map, and design guidelines, consult the SI2166-D60-GMR datasheet and Silicon Labs reference designs.

There are no guaranteed pin‑for‑pin drop‑in equivalents to the Silicon Labs SI2166‑D60‑GMR. Comparable demodulator/tuner IC families are offered by Broadcom (BCM series), MaxLinear (MxL series), NXP (TDA/TDAxxxx series) and STMicroelectronics (STB/STA series). Verify standards, interfaces, pinout and firmware compatibility via datasheets or consult Silicon Labs for recommended replacements.
