SI21622-C60-GMR

Video Processing Overview

The Si21622-C60-GMR is a dual digital TV demodulator integrating separate high-performance cores for DVB-T2/T and DVB-C2/C standards into a single compact package. It leverages Skyworks' proven architecture to minimize front-end design complexity, cost, and power dissipation while achieving excellent reception performance. The device supports standard IF or low-IF inputs and includes an on-chip blind scanning algorithm for DVB-C with a blind lock function. It features two independent programmable transport stream interfaces compatible with all MPEG decoders or conditional access modules.

Video Processing Feature Summary

• Pin-to-pin and API compatible with the entire Si216x2 and Si218x2 dual demodulator families
• Supports NorDig Unified 2.5 and D-Book 8 compliance for both terrestrial and cable standards
• Features fast lock times and upgradeable firmware via SPI or I2C broadcast mode
• Includes dual independent differential IF inputs and GPIOs for flexible tuner integration

Video Processing Applications

• Multi-receiver integrated digital televisions (iDTV) mounted on-board or in a NIM
• Advanced multimedia personal video recorder set-top boxes (PVR STBs)
• PC-TV accessories and hybrid receivers
• Personal video recorders, DVD players, and Blu-Ray disc recorders

Video Processing Procurement Notes

Verify the specific ordering suffix required for tape-and-reel packaging versus tube configuration. Confirm that the selected variant meets the environmental compliance requirements for your target market. Ensure the supply chain source provides official documentation to validate the component's authenticity and revision status before integration into production designs.

Video Processing Selection Notes

Select this component when a single chip solution is needed to handle both terrestrial and cable digital broadcasting standards simultaneously. It is ideal for designs requiring pin compatibility with existing Si216x2 or Si218x2 implementations to simplify board upgrades. Choose this part if the application demands low power consumption and reduced external component count for cost-sensitive consumer electronics.

Video Processing Part Context

This device belongs to Skyworks' advanced digital TV demodulator portfolio, designed to replace multiple discrete components. It consolidates the functionality of separate terrestrial and cable demodulators into one QFN-68 package. The Si21622 series represents a generation of highly integrated solutions aimed at reducing system-level bill of materials for modern television hardware manufacturers.

Video Processing Replacement Considerations

Official substitutes include other members of the Si216x2 and Si218x2 family which share pin and API compatibility. Verify that any replacement part supports the specific DVB-T2/T and DVB-C2/C modes required by the design. Ensure the alternative package variant matches the thermal and mechanical constraints of the existing footprint.
