Additional Details:

The SI2141-B10-GM typically operates with a supply voltage of 3.3V. It features a highly linear RF front-end that minimizes distortion and maximizes signal quality. The integrated LNA provides excellent sensitivity, allowing for reception of weak signals. The on-chip tracking filters suppress unwanted signals and interference. It supports various output interfaces, such as I2C for control and IF (Intermediate Frequency) for signal output. The device is available in a small QFN package. The specific TV standards supported, frequency range, and other performance characteristics can be found in the product datasheet.
