DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC2775GR/GS FREQUENCY DOWN CONVERTER FOR VHF-UHF BAND TV/VCR TUNER DESCRIPTION The µPC2775GR/GS are Silicon monolithic ICs designed for TV/VCR tuner applications. These ICs consist of double balanced mixers (DBM), local oscillator, preamplifiers for prescaler operation, IF amplifier, regulator, UHF/ VHF switching circuit, and so on. These one chip ICs cover a wide frequency band from VHF to UHF bands. These ICs are packaged in a 20 pins SSOP (shrink small outline package; µPC2775GR) or 20 pins SOP (small outline package; µPC2775GS) suitable for surface mounting. So, these ICs enable to produce economical and physically small or high-density VHF - UHF tuner and reduce the tuner development time. FEATURES • VHF to UHF band operation. • Low oscillation frequency drift against supply voltage and temperature fluctuation due to balanced type UHF oscillator. • These ICs can be used in single ended or differential IF outputs. • Supply voltage: 9 V • Packaged in 20 pins SSOP or 20 pins SOP suitable for surface mounting ORDERING INFORMATION PART NUMBER PACKAGE PACKAGE STYLE µPC2775GR-E1 20 pin plastic SSOP (225 mil) Embossed tape 12 mm wide, 2.5 k/REEL Pin 1 indicates pull-out direction of tape µPC2775GS-E1 20 pin plastic SOP (300 mil) Embossed tape 24 mm wide, 2.5 k/REEL Pin 1 indicates pull-out direction of tape Caution electro-static sensitive device The information in this document is subject to change without notice.

The Specific quality grade applies only to devices developed based on a customer designated “quality assurance program“ for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. M7 98.8
