TDA18260HN集成電路（IC）的視頻處理規(guī)格書PDF中文資料

General description

The TDA18260HN is a dual silicon tuner IC designed specifically for high definition

multi-tuner cable Set-Top Boxes (STBs) supporting single streaming and multi-streaming

PVR STBs with watch, record, video-on-demand and in-home video distribution capability.

Used in conjunction with the TDA10025HN (dual digital channel demodulator), the

TDA18260HN covers all worldwide digital cable standards.

? The TDA18260HN ensures a low system cost as:

– Costly components such as low noise amplifiers, Surface Acoustic Wave (SAW)

filters and incremental crystal oscillators have been eliminated from the system Bill

Of Materials (BOM)

? The TDA18260HN high performance silicon tuner meets today’s digital cable TV

reception needs with:

– Matched performance levels for master and slave tuners

– Low power consumption

– High linearity

– Low noise figure

? The TDA18260HN ensures ease of use with:

– Easy on-board integration

– Efficient and effective PCB design

– Reduced external components

Features and benefits

? Dual tuner inside one single, small sized package

? One single RF input with direct cable connection

? Internal splitter to drive the two integrated tuners

? Two low IF outputs, connecting directly to demodulators

? RF loop-through

? Easy application for up to 6-tuner using 3 TDA18260HN

? Dedicated multiple tuner outputs to drive additional tuners

? No need for external active splitter

? Same performance on all streams

? Extended frequency coverage from 42 MHz up to 1002 MHz

? Multistandard cable receptions

? Enhanced filtering scheme with no external components

? Third and fifth signal harmonics suppression

? Optimum adjacent channel rejection

? MoCA rejection reduces the complexity and the cost of the triplexer

? Single 3.3 V power supply with low power consumption

? Single crystal application for up to 6 streams, including demodulators

? High accuracy Received Signal Strength Indicator (RSSI)

? Dual I2C-bus provides full flexibility in programming the two streams from one SoC or

independently from two SoCs
