The TDA18250BHN/C1K from NXP Semiconductors is a silicon tuner IC specifically designed for worldwide cable and terrestrial digital Set Top Boxes (STB). It operates with a single 3.3V supply voltage and features an I2C-bus interface compatible with 3.3V microcontrollers.
This tuner IC offers RF frequency coverage up to 1 GHz and a flexible low IF output ranging from 3 MHz to 7.5 MHz, facilitating matching with various demodulators. It boasts a low noise figure of 3.8 dB typical and high immunity to wireless interferers like WLAN, LTE, and GSM. The device integrates essential components such as Low-Noise Amplifiers and SAW filters, reducing system cost and external component count.
Designed for ease of use, the TDA18250BHN/C1K allows for easy on-board integration and efficient PCB design. It includes features like a crystal oscillator output buffer, Slave Tuner Output (STO) for dual tuner applications, and fully integrated oscillators. The tuner also provides enhanced ESD protection (8 kV HBM) on RF_IN and LT pins.
The TDA18250BHN/C1K is available in a 32-HVQFN (5x5) package and is suitable for surface mount applications. Its design aims to meet current and future digital cable and terrestrial TV reception requirements with low-power consumption and high linearity.
