The Si2107/08/09/10 are a family of pin-compatible, complete front-end solutions

for DSS and DVB-S digital satellite reception. The IC family incorporates a tuner,

demodulator, and LNB controller into a single device resulting in significantly

reduced board space and external component count. 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.
