Overview Technical Documents
 

 
 
Intel® CE 6354 The Intel® CE 6354 DVB-T demodulator builds on the high performance standards set by Intel’s CE 6355 NorDig Unified 1.0.2 component by incorporating a Maximum Ratio Combining (MRC) processor that enables up to four CE 6354 DVB-T demodulators to be cascaded together. This feature significantly improves the signal handling performance of the solution compared to single demodulator designs, to facilitate portable “anywhere” TV reception.

The Intel CE 6354 DVB-T demodulator 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 6354 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.

Terrestrial receiver application
 
Intel supports the Intel CE 6354 DVB-T demodulator with a two-device reference design that lets you quickly evaluate the improved performance offered by diversity over single demodulator operation. 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 6354 DVB-T demodulator has a unique on-chip dedicated tuner drive engine, ideal for the control of MOPLL-based RF tuner designs. This significantly reduces the tuner control software overhead and results in very fast frequency channel scan performance. For the non-MOPLL-based tuner, the Intel CE 6354 DVB-T demodulator incorporates a two-wire bus bypass mode, that enables direct unrestricted programming.

The Intel CE 6354 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 6354 demodulator’s integrated digital filter 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 6354 can be directly interfaced in parallel or serial modes to all standard MPEG-2 processing chips.
