Si2108

Notes:
1. Permanent damage may occur if the absolute maximum ratings are exceeded. Functional operation should be restricted to the conditions as specified in the operations sections of this data sheet. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
2. The Si2107/08/09/10 is a high-performance RF integrated circuit. Handling and assembly of these devices should
only be done at ESD-protected workstations.

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 Si2107/08/09/10 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.
