BIPOLAR DIGITAL INTEGRATED CIRCUIT
µPB1505GR
3.0 GHz PRESCALER DIVIDED BY 256, 128, 64
FOR BS/CS TUNER
DESCRIPTION
µPB1505GR is a silicon prescaler IC operating up to 3.0 GHz and divided by 256, 128, 64. Due to 3.0 GHz operation and
high division, this IC can contribute to produce BS/CS tuners with kit-use of 17K series DTS controller or standard CMOS
PLL IC. The package is 8 pin plastic SOP suitable for surface mounting.
This IC is manufactured using NEC’s 20 GHz fT NESAT III silicon bipolar process. This process uses silicon nitride
passivation film and gold electrodes. These materials can protect the chips from external pollution and prevent corrosion/
migration. Thus, this IC has with excellent performance, uniformity and reliability.

NOTE ON 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 track length of the ground pins as short as possible.
(4) Connect a bypass capacitor (e.g. 1 000 pF) to the VCC pin.

• 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: 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.
