Description
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. Si2109/10 versions
include a hardware channel scan accelerator for fast “blindscan”. The Si2107/08/
09/10 family features new channel detection and acquisition technology:
QuickLock for Si2107/08/09/10 and QuickScan for Si2109/10. QuickLock
achieves fast channel acquisition and QuickScan, fast channel detection. An I
bus interface is used to configure and monitor all internal parameters.
