SI2164-C60-GMR

Video Processing Overview

The Si2164-C60-GMR is a digital TV demodulator integrating support for DVB-T/T2, DVB-C/C2, and DVB-S/S2/S2X standards on a single CMOS die. It operates with two power supplies of 1.2 V and 3.3 V within an ambient temperature range of –10 to 75 °C. The device accepts input clock references between 4 and 30 MHz and utilizes a 7x7 mm QFN-48 pin package. Total power consumption varies by standard, ranging from 14 mW in DVB-C mode to 421 mW in DVB-S2 mode.

Video Processing Feature Summary

• Integrates digital demodulators for all first and second generation DVB standards including T2, C2, S2, and S2X.
• Supports advanced modulation schemes up to 4096-QAM for cable and APSK for satellite reception.
• Features on-chip blind scan algorithms and fast lock times for efficient signal acquisition.
• Includes DiSEqC 2.0 interface and Unicable support for comprehensive satellite dish control.

Video Processing Applications

• Integrated circuit design for intelligent digital televisions (iDTV).
• Advanced multimedia set-top boxes and personal video recorders.
• Blu-ray disc recorders requiring high-performance demodulation.
• PC-TV accessories and hybrid tuner modules.

Video Processing Procurement Notes

Verify the specific ordering suffix matches the required package type and compliance status. Confirm firmware version compatibility with existing host systems. Ensure thermal management strategies align with the specified resistance values for the target PCB layer count. Check for any recent product change notifications affecting pin assignments or electrical characteristics.

Video Processing Selection Notes

Select this component when a single chip solution is required for multi-standard DVB reception. Consider the low power consumption profiles for battery-operated or thermally constrained designs. Evaluate the I2C interface requirements against the host controller capabilities. Verify that the supported bandwidths and symbol rates meet the specific broadcast standards of the deployment region.

Video Processing Part Context

This part belongs to the Si2164C family of digital TV demodulators manufactured by Skyworks Solutions. It is designed as a cost-optimized front-end solution for television receivers. The device is pin-to-pin compatible with other members of the Si216x/8x single demodulator family, facilitating easier upgrades or design iterations within the same product line.

Video Processing Replacement Considerations

Official substitutes include other variants within the Si2164C series such as the Si2164-C60-GM. Ensure replacement parts maintain API compatibility with existing software drivers. Verify that the physical footprint and pinout remain identical to avoid PCB redesign.
