Silicon Laboratories Inc. announces the first product in its SiRX™ product family, a fully-integrated single-chip satellite RF front-end for direct broadcast satellite (DBS). Offering good performance and small size, the Si21xx devices are suited 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 SiRX satellite RF front-end integrates a high-performance satellite L-band RF tuner, a dual-mode DVB-S/DSS digital demodulator and a power-efficient, step-up supply controller for the low-noise block converter (LNB) into a single 6 × 8 mm CMOS solution. The integration of the LNB supply controller is believed to be an industry-first and includes support for DiSEqC 2.x and legacy tone/voltage LNB signaling. The SiRX devices also support an on-chip hardware blindscan feature that improves channel scan time by a factor of 10 when compared to many existing solutions.
