SI21692-D60-GM

Video Processing Overview

The Si21692-D60-GM is a dual digital TV demodulator integrating two separate high-performance demodulators for DVB-T2/T/C, DVB-S2/S, and DVB-S2X standards. It operates with power supplies of 1.2 V and 3.3 V within an 8x8 mm QFN-68 package. The device supports bandwidths of 1.7, 5, 6, 7, or 8 MHz for terrestrial/cable and symbol rates from 1 to 45 MSps for satellite. Input clock reference ranges from 4 to 30 MHz, with supported crystal frequencies between 16 and 30 MHz.

Video Processing Procurement Notes

Verify the specific ordering suffix (GM) against official Skyworks documentation to confirm package type and compliance status. Confirm availability through authorized distributors as supply may be restricted. Ensure firmware compatibility requirements are met for API integration with existing single or dual demodulator families.

Video Processing Selection Notes

Select this component for designs requiring simultaneous reception of terrestrial/cable and satellite signals in a compact form factor. It is suitable for applications needing NorDig Unified 2.5 and D-Book 8 compliance. Consider its pin-to-pin compatibility with other Si216x2 and Si218x2 family members for design flexibility.
