SI2157-A30-GMR

Video Processing Overview

The SI2157-A30-GMR is a universal hybrid TV tuner supporting digital and analog reception for worldwide terrestrial and cable standards. It integrates a digital low-IF architecture with a fifth-generation RF front-end to deliver industry-leading second-order distortion performance. The device requires no external balun, tracking filters, LNAs, SAW filters, or inductive power supply filtering. It operates on 3.3 V and 1.8 V supplies or a single 3.3 V option, featuring an integrated power-on reset circuit and high immunity to Wi-Fi and LTE interference.

Video Processing Feature Summary

• Supports worldwide digital and analog TV standards including ATSC, DVB-T2/C2, ISDB-T/C, DTMB, NTSC, and PAL/SECAM
• Delivers industry-leading phase noise performance and superior real-world reception tolerance
• Achieves lowest bill of materials by eliminating the need for external baluns, SAW filters, wire-wound inductors, and discrete LNAs
• Provides high immunity to Wi-Fi and LTE interference through a harmonic rejection mixer

Video Processing Applications

• Hybrid ½-NIM tuner module
• Integrated Digital TV (iDTV)
• Hybrid terrestrial and cable set-top boxes
• Hybrid PVR, DVD, and Blu-Ray disc recorders
• PC-TV accessories

Video Processing Procurement Notes

Verify the specific suffix 'A30-GMR' against the manufacturer's official documentation to confirm exact packaging, tape-and-reel specifications, and environmental compliance status. Ensure compatibility with existing system designs regarding pin assignments and API requirements before procurement.

Video Processing Selection Notes

Select this component for designs requiring comprehensive global standard support within a minimal footprint. It is suitable for applications demanding high immunity to wireless interference and reduced component count. Verify that the target system can accommodate the required 3.3 V and 1.8 V power rails or utilizes the single-supply configuration.

Video Processing Part Context

The SI2157 series represents a generation of hybrid tuners from Silicon Laboratories, succeeding earlier models like the Si2151. It maintains pin and API compatibility with previous generations to minimize customer development effort while offering enhanced integration and performance metrics compared to discrete MOPLL-based solutions.
