BIPOLAR DIGITAL INTEGRATED CIRCUIT
PB1510GV
3 GHz INPUT DIVIDE BY 4 PRESCALER IC FOR DBS TUNERS
The PB1510GV is a 3.0 GHz input divide by 4 prescaler IC for DBS tuner applications. The PB1510GV is suitable for use of frequency divider for PLL synthesizer block. The PB1510GV is a shrink package version of the
PB585G so that this small package contributes to reduce the mounting space.
The PB1510GV is manufactured using NEC's high fT NESATTM IV silicon bipolar process. This process uses silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
* * * * High toggle frequency Low current consumption Fixed division : fin = 0.5 GHz to 3.0 GHz : 5 V, 14 mA TYP. : /4 High-density surface mounting : 8-pin plastic SSOP (175 mil)
APPLICATION
* * Prescaler between local oscillator and PLL frequency synthesizer included modulus prescaler DBS tuners with kit use of VHF/UHF band PLL frequency synthesizer

NOTE CORRECT USE (1) Observe precautions for handling because of electro-static sensitive devices. (2) Form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired operation). (3) Keep the wiring length of the ground pins as short as possible. (4) Connect a bypass capacitor (e.g. 1 000 pF) to the VCC pin. RECOMMENDED SOLDERING CONDITIONS This product should be soldered under the following recommended conditions. For soldering methods and conditions other than those recommended below, contact your NEC sales representative.

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". 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: Aircrafts, 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. Anti-radioactive design is not implemented in this product.
