LA7784-MPB-E-SY

RF Mixers Overview

The LA7784-MPB-E-SY is a downconverter integrated circuit designed for digital CATV applications. It accepts RF input frequencies ranging from 50 to 150 MHz and supports DOCSIS (USA) and Euro-DOCSIS standards. The component is housed in a 28-pin LSSOP package with dimensions of 15 mm length and 1.7 mm maximum seating height. It operates within a temperature range of -20 °C to 70 °C and requires a maximum supply voltage of 5.5 V.

RF Mixers Feature Summary

• Integrated downconversion functionality for digital cable television signals
• Supports both US DOCSIS and Euro-DOCSIS protocol standards
• Microprocessor-based controller architecture

RF Mixers Applications

• Digital CATV headend systems
• RF signal downconversion for cable infrastructure
• DOCSIS-compliant cable modem front-ends

RF Mixers Procurement Notes

Verify the specific suffix '-SY' against official Sanyo or onsemi documentation, as standard listings often reference 'LA7784-MPB-E'. Confirm that the variant retains the same pinout and electrical characteristics as the base LA7784 model. Ensure the source document explicitly defines the '-SY' designation to avoid receiving a functionally different or obsolete revision.

RF Mixers Selection Notes

Select this component for digital CATV environments requiring standardized DOCSIS compatibility. The 28-pin LSSOP package suits space-constrained PCB layouts. Verify that the operating temperature range of -20 °C to 70 °C meets the environmental requirements of the target installation site before finalizing the design.

RF Mixers Part Context

This part belongs to the LA7784 series of downconverter ICs originally manufactured by Sanyo Semicon Device. The product line has been transitioned to onsemi following corporate restructuring. The LA7784 serves as a specialized solution for converting high-frequency RF signals to lower intermediate frequencies suitable for digital processing in cable TV networks.
