TA1267AF MULTISTANDARD PIF / SIF SYNCHRONOUS DEMODULATOR IC
The TA1284FN TV tuner IC is designed to facilitate the reception of television signals across various frequency bands, specifically VHF, UHF, and CATV. The integration of multiple functions into a single chip significantly simplifies circuit design, reduces component count, and minimizes the overall footprint of the tuner module. The 16-pin SSOP (Shrink Small Outline Package) form factor is particularly advantageous for applications where space is at a premium, such as in portable devices or compact television receivers.
The mixer and oscillator for the VHF and CATV bands work in tandem to effectively convert incoming RF signals to a lower intermediate frequency, which is then amplified by the integrated IF amplifier. This amplification stage is crucial for enhancing signal quality and ensuring that the processed signal is strong enough for further demodulation and decoding.
Operating at a supply voltage of 5 V, the TA1284FN is optimized for low power consumption, making it suitable for battery-operated devices as well as energy-efficient applications. The reduced power dissipation not only aids in thermal management but also extends the operational lifespan of the device by minimizing heat-related issues.
Overall, the TA1284FN represents a versatile solution for modern television tuners, providing essential functionality within a compact, efficient package, and is well-suited for integration into a variety of consumer electronics.The TA1284FN is TV Tuner IC which integrate mixer / Oscillator for VHF and CATV bands, mixer / Oscillator for UHF band, and IF Amplifier on a single chip. Supply voltage of 5 V helps lower power dissipation from the set. Compact 16-pin SSOP makes the Tuner more compact. By Toshiba Semiconductor 🔗 External reference
