Intel® CE 6353
DVB-T Demodulator
Overview Technical Documents

Intel® CE 6353 The Intel® CE 6353 DVB-T demodulator meets the performance requirements of NorDig Unified 1.0.2 standard. The device includes a high-performance 10-bit A/D converter capable of accepting direct IF integrated digital filtering and requires only a single 8 MHz channel SAW filter for 6, 7 and 8 MHz COFDM signal reception, plus a 7-bit ADC for RF level indication. An advanced hard-wired on-chip state machine controls all acquisition and tracking operations, minimizing software overhead and resulting in fast auto scan and auto signal re-acquisition.

The Intel CE 6353 DVB-T demodulator also features excellent single-frequency network SFN performance, unique auto active impulse noise filtering and very low power consumption, including software/hardware power-down mode.
Product information
Terrestrial receiver application
Intel supports the Intel® CE 6353 DVB-T demodulator with four reference designs from can tuner¹ manufacturers Panasonic, Philips, Samsung and Thomson. These reference designs enable you to quickly evaluate and implement the DVB-T standard for your terrestrial applications. Each board includes complete documentation and test results, with software supported directly by Intel.

Our DVB-T reference designs offer excellent signal handling performance at very low power consumption. The Intel CE 6353 DVB-T demodulator has a unique on-chip dedicated tuner drive engine, ideal for the control of MOPLL-based RF tuner designs. This vastly reduces the tuner control software overhead and results in very fast frequency channel scan performance. For the non-MOPLL-based tuner, the Intel CE 6353 DVB-T demodulator incorporates a two-wire bus bypass mode, enabling direct unrestricted programming of the tuner.

The Intel CE 6353 DVB-T demodulator accepts the classic TV IF frequencies of 36/44 MHz and low IF down to 4.57 MHz. It provides tuner IF AGC control, and RF AGC read using a 7-bit ADC for calculated RF signal strength indication. The Intel CE 6353 DVB-T demodulator also includes an integrated digital filter that reduces the bill of materials by eliminating the need for multi-bandwidth SAW IF channel filters. It provides 6, 7 and 8 MHz operation using a single 8 MHz SAW filter. Driven by high-level commands and featuring full automation, the Intel CE 6353 DVB-T demodulator can be directly interfaced in parallel or serial modes to all standard MPEG-2 processing chips.
