DESCRIPTION

· The TDA18275 is a high-performance silicon tuner for terrestrial and cable TV reception, supporting both analog and digital broadcasts.

· It delivers a Low IF (LIF) signal to demodulators, facilitating TV design with on-board integration, reduced BOM, and system solution flexibility.

FEATURES

· Single 3.3 V supply voltage.
· Worldwide multistandard terrestrial and cable capabilities.
· Alignment-free, RoHS compliant, and I2C-bus interface compatible with 3.3 V microcontrollers.
· Fully integrated oscillators and RF selectivity.
· Dual IF output ports and programmable General-Purpose Outputs (GPO).
· Supports 1.7 MHz to 10 MHz channel bandwidths and LIF center frequency from 0.8 MHz to 7.5 MHz.
· Integrated IF selectivity, eliminating external SAW filters.
· Single-ended RF input, excellent return loss, and embedded Power Level Detector (PLD).
· Integrated gain control, self-AGC synchronization mode, and fast tuning time.
· Strong immunity to LTE and WLAN interferers.

APPLICATIONS

· Terrestrial and cable TV reception for analog and digital broadcasts.
· Integration into TV systems with flexible IF filtering for various demodulators.
