The IC family incorporates a tuner, demodulator, and LNB controller into a single device resulting in a significant reduction in board space and external components. The device supports symbol rates of 1 to 45 MBaud over a 950 to 2150 MHz range. A full suite of features including automatic acquisition, fade recovery, blind scanning, performance monitoring, and DiSEqC Level 2.2 compliant signaling are supported. The Si2108/10 further add short-circuit protection, overcurrent protection, and a step-up dc-dc controller to implement a low-cost LNB supply solution. Si2110/09 versions include a hardware channel scan accelerator for fast “blindscan”. An I2C bus interface is used to configure and monitor all internal parameters. The Si2107/08/09/10 provides a complete front end solution for DVB-S and DSS receivers encompassing the functionality of a satellite network interface module (NIM), with additional LNB power supply regulator functionality. By integrating the RF synthesizer and PLL (including the loop filter), eliminating the analog I/Q signal interface and the control loop interfaces between tuner and demodulator (AGC, clock synchronization), the product family uses minimal external BOM, resulting in a low-cost and easy-to-use satellite RF receiver solution.
