SI21602-C60-GM

Video Processing Overview

The Si21602-C60-GM is a dual universal digital TV demodulator integrating two independent high-performance demodulators for DVB-C2, C, T, S2, S2X, and S standards into a single QFN-68 package. It supports input clock references from 4 to 30 MHz and operates with power supplies of 1.2 V and 3.3 V. The device features separate differential IF inputs for terrestrial/cable tuners and zero-IF I/Q inputs for satellite tuners. It includes blind scanning algorithms, DiSEqC 2.x interfaces, and flexible transport stream outputs.

Video Processing Feature Summary

• Pin-to-pin and API compatible with the entire Si216x2 and Si218x2 dual demodulator families
• Integrates on-chip blind scanning and lock functions for DVB-S/S2/S2X and DVB-C standards
• Supports channel bonding for transport stream transmission and Unicable systems
• Features upgradeable firmware via fast SPI or I2C broadcast mode

Video Processing Applications

• Multi-receiver integrated digital televisions (iDTV) in onboard or NIM configurations
• Advanced multimedia personal video recorder set-top boxes (PVR STBs)
• PC-TV accessories and hybrid receiver solutions
• PVR, DVD, and Blu-Ray disc recorders

Video Processing Procurement Notes

Verify the specific ordering suffix against the manufacturer's current selection guide to ensure correct packaging and RoHS compliance status. Confirm that the required firmware patches are available for download via SPI or I2C if upgrading legacy designs. Check thermal resistance specifications relative to your PCB layer count to ensure adequate heat dissipation.

Video Processing Selection Notes

Select this component when a unified solution for both terrestrial/cable and satellite reception is required within a compact footprint. Ensure the host system provides the necessary 1.2 V and 3.3 V power rails. Verify compatibility with existing MPEG decoders or conditional access modules through the flexible serial or parallel transport stream interfaces.

Video Processing Part Context

This device belongs to Skyworks' proven digital demodulation architecture, serving as an evolution of the widely used Si2164/67/68/69 series. It is designed to minimize front-end design complexity by connecting directly to dual terrestrial/cable and dual satellite tuners. The chip replaces discrete demodulation solutions, offering a cost-optimized and power-efficient approach for modern TV front-ends.

Video Processing Replacement Considerations

The Si21602-C60-GM is pin-to-pin compatible with other devices in the Si216x2 and Si218x2 dual demodulator families. When substituting, verify that the alternative part number maintains API compatibility with the existing software drivers and firmware configuration files.
