SI21672-D60-GM

Video Processing Overview

The Skyworks SI21672-D60-GM is a dual digital TV demodulator integrating separate high-performance demodulators for DVB-T/C, DVB-S2/S, and DVB-S2X standards. It operates with two power supplies: VDD_VCORE (1.14–1.30 V) and VDD_VANA/VDD_VIO (3.00–3.60 V). The device supports input clock references from 4 to 30 MHz and crystal frequencies of 16 to 30 MHz. Power consumption per demodulator varies by standard: DVB-T1 at 182 mW, DVB-C2 at 142 mW, DVB-S2 at 421 mW, and DVB-S at 230 mW. It features a QFN-68 package measuring 8x8 mm.

Video Processing Feature Summary

• Integrates two independent demodulators supporting DVB-T/C, DVB-S2/S, and DVB-S2X standards within a single compact package.
• Includes on-chip blind scanning algorithms for DVB-S/S2/S2X and DVB-C standards, along with blind lock functionality.
• Provides dual DiSEqC 2.x interfaces for satellite dish control and Unicable support.
• Features two independent programmable transport stream interfaces with cross-bar functionality compatible with MPEG decoders.

Video Processing Applications

• Multi-receiver iDTV systems
• Advanced multimedia PVR set-top boxes
• PC-TV accessories
• PVR, DVD, and Blu-Ray disc recorders

Video Processing Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and reel/tray configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure firmware patch download capabilities via SPI or I2C are supported in the target application design.

Video Processing Selection Notes

Select this component for designs requiring simultaneous reception of terrestrial/cable and satellite signals. It offers pin-to-pin compatibility with other Si216x2 and Si218x2 family members. API compatibility extends across single and dual demodulator families, simplifying migration. Verify thermal resistance requirements for the specific PCB layer count used in the final assembly.

Video Processing Part Context

The SI21672-D60 belongs to the Skyworks Si21672 series of dual universal digital TV demodulators. It leverages proven digital demodulation architecture to minimize front-end design complexity and power dissipation. The device connects to dual terrestrial/cable tuners and dual satellite tuners, providing a cost-optimized TV front-end solution.

Video Processing Replacement Considerations

The datasheet confirms pin-to-pin compatibility with all dual demodulator family members, specifically the Si216x2 and Si218x2 series. API compatibility also exists with all single and dual demodulators in the broader product line.
