Description
Note: these products are no longer recommended for new designs. Existing customers can receive limited technical support from their local sales or distributor representative.

​The Si21xx satellite receiver product family is the industry's first fully-integrated single-chip satellite RF front-end solution for direct broadcast satellite (DBS).

Offering the highest performance, smallest size and easiest-to-use receiver solution for DBS, the Si21xx devices are ideal for all free-to-air (FTA) and pay-TV DBS equipment including satellite set-top boxes, PC cards for satellite TV, DBS receivers for automotive or avionic use, DVD recorders and digital TVs with integrated satellite receivers.

The satellite receiver family incorporates a tuner, demodulator and LNB controller into a single chip, resulting in a significant reduction in board space and external components. The IC supports symbol rates of 1 to 45 MBaud over a 950 to 2150 MHz range. The ICs support a full suite of features including automatic acquisition, fade recovery, blind scanning, performance monitoring and DiSEqC™ Level 2.2 compliant signaling. The Si2108/10 ICs further add short-circuit protection, overcurrent protection and a step-up dc-dc controller to implement a low-cost LNB supply solution. Si2109/10 versions include a hardware channel scan accelerator for fast "blindscan". An I²C bus interface is used to configure and monitor all internal parameters.
