– 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
