BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC1862
BURST LOCK CLOCK GENERATOR
The µPC1862 is an LSI incorporating a PLL circuit to generate nfSC clocks (fSC: color subcarrier frequency), ideal
for the processing of digital video signals as in extended definition television (EDTV) systems.
FEATURES
• VCO is incorporated.
• Horizontal and vertical sync separation circuits are incorporated (with output pins).
• Horizontal and vertical sync output pulses (TTL level)
• ACC amplifier and killer detector circuits are incorporated.
• 1/4 and 1/8 (1/2 × 1/4) frequency dividers are incorporated.
• fSC phase control circuits is incorporated.
• Applicable to both NTSC and PAL systems.
• Possible to input burst gate pulse from external

CAUTION AT DESIGNING
Resonators
NEC evaluates µPC1862 using resonators which are shown below in design and development process.
If the different product is used as a resonator, electrical specification value described in this document is not assured.
And when connecting resonator to external circuit, there is need to consider temperature specification, voltage
fluctuation and product variation. In this case, normal operation is not assured in the application circuit including the
different product.
Use the resonators which are shown below when you design circuit.

µPC1862
Recommended pattern
The µ PC1862 generates system clock for synchronous signal processing and clock generate processing.
If the supply voltage, line placement and routing are not set appropriately that the µPC1862 cannot generate correct
system clock.
Though the recommended pattern is not shows in this document, note points shown below at designing.
26
1.
For synchronous section and chroma section, each power supply must be isolated.
2.
Lines to pin 9 to pin 13 should be as thick and short as possible.
3.
Connect resonator as near IC as possible. Don’t put GND line between resonator pins for parasitism capacitance.

If you don’t use Sync pin but use Chroma pin on µPC1862, you process pin 19 to pin 36 as follows. In this case, you
need to input a pin 24 with burst gate pulse from external.
In this application, you can’t use output of pin 20 to pin 23.

this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. 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.
