Description
LNB2/DRC RESET PWM/DCS
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 sol...
