SI21692-D63-GMR

Video Processing Overview

The Skyworks SI21692-D63-GMR is a dual digital TV demodulator integrating separate high-performance receivers for DVB-T2/T/C and DVB-S2/S/S2X standards. It operates on two power supplies: VDD_VCORE (1.14 to 1.30 V) and VDD_VANA/VDD_VIO (3.00 to 3.60 V). The device supports bandwidths of 1.7, 5, 6, 7, or 8 MHz for terrestrial/cable modes and symbol rates from 1 to 45 MSps for satellite standards. It features differential IF inputs for T/C tuners and zero-IF I/Q inputs for satellite tuners.

Video Processing Feature Summary

• Integrates two independent demodulators supporting DVB-T2, T2-Lite, T, C, S2, S2X, and S standards within a single package.
• Includes dual DiSEqC 2.x interfaces and an equalizer to compensate for echoes in long cable feeds from the LNB.
• Provides flexible transport stream outputs with serial or parallel modes and cross-bar functionality compatible with MPEG decoders.
• Supports firmware upgrades via fast SPI or I2C and includes blind scanning algorithms for DVB-S/S2/S2X and DVB-C.

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 suffix 'GMR' against official Skyworks documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the required pinout and interface configuration. Confirm availability through authorized distributors as lead times may vary. Validate that the component meets all regulatory requirements for the target market before finalizing procurement.

Video Processing Selection Notes

Select this component when a compact solution is needed to receive both terrestrial/cable and satellite signals simultaneously. It is suitable for designs requiring NorDig Unified 2.5 and D-Book 8 compliance. The dual demodulator architecture minimizes front-end complexity compared to using separate chips. Ensure the design accommodates the QFN-68 package dimensions and thermal requirements.

Video Processing Part Context

This device belongs to the Si21692D family, which is pin-to-pin compatible with other dual demodulators like the Si216x2 and Si218x2 series. It shares API compatibility with Skyworks' single and dual demodulator lines, facilitating easier migration between different product variants within the same ecosystem.

Video Processing Replacement Considerations

Pin-to-pin compatible replacements include other members of the Si216x2 and Si218x2 dual demodulator families. Verify functional equivalence regarding supported standards and interface configurations before substitution.
