TDA18250HN
Cable Silicon Tuner
Rev. 6 — 22 December 2011
Product short data sheet
1. General description
The TDA18250 is a silicon tuner IC designed specifically for high definition cable Set-Top
Boxes (STB) supporting single streaming.
Used in conjunction with a digital channel demodulator, the TDA18250 covers all
worldwide digital cable standards.
•
The TDA18250 ensures a low system cost as:
–
Costly components such as low-noise amplifiers, Surface Acoustic Wave (SAW)
filters are eliminated from the system BOM
•
The TDA18250 high-performance silicon tuner meets today’s digital cable TV
reception needs with:
–
Low power consumption
–
High linearity
–
Low noise figure
•
The TDA18250 ensures ease of use with:
–
Easy on-board integration
–
Efficient and effective PCB design
–
Reduced external components

with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification —
The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors accepts no liability for inclusion and/or use of
NXP Semiconductors products in such equipment or applications and
therefore such inclusion and/or use is at the customer’s own risk.
Applications —
Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the

customer(s). NXP does not accept any liability in this respect.
Limiting values —
Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
