TDA18275 Hybrid (analog and digital) silicon tuner for terrestrial and cable TV reception Rev. 2 14 October 2013 Product short data sheet 1. General description The TDA18275 is a high performance silicon tuner designed for terrestrial and cable TV reception for both analog and digital broadcasts. The TDA18275 supports all analog and digital TV standards and delivers a Low IF (LIF) signal to a demodulator for analog TV and/or a channel demodulator for digital TV. The TDA18275 facilitates TV design by: Allowing on-board integration Drastically reducing the tuner Bill Of Material (BOM) Providing flexibility in system solution development 2. Features and benefits Single 3.3 V supply voltage Worldwide multistandard terrestrial and cable capabilities Alignment free RoHS compliant 2 I C-bus interface compatible with 3.3 V microcontrollers Fully integrated oscillators Fully integrated RF selectivity (no need for RF tracking filters coils) 2 programmable General-Purpose Outputs (GPO) Dual IF output ports 1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths LIF channel center frequency output ranging from 0.8 MHz to 7.5 MHz Fully integrated IF selectivity eliminating the need for external SAW filters Large flexibility in the IF filtering stage to ease the matching with various demodulators circuits Single-ended RF input, no need for external balun Excellent return loss compatible with cable requirements Power Level Detector (PLD) embedded Integrated gain control Self-AGC synchronization mode (VSync) for analog reception Very fast tuning time Strong immunity to LTE interferers in the digital dividend bandwidth Strong immunity to WLAN interferers (802.11 a/b/g/n)TDA18275 NXP Semiconductors Hybrid silicon tuner for terrestrial and cable TV reception 3.
