DVB-T demodulator
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.
Fellet believed Sky would need to hand the spectrum back to the Government by 2015 if it didn't find a use for it, under a rule that meant it had to either "use it or lose it".
The spectrum became largely surplus to requirements after Sky closed its analogue pay-television service in March last year. Sky will need to cease free-to-air analogue broadcasts of Prime Television by November 2013, the deadline by which all television channels in all parts of the country will need to switch to digital transmission.
Fellet said Sky could not easily offer customers a lower-cost service offering fewer channels than its "basic" package through its satellite service because of its licensing agreements with channel owners, which meant it had to offer "all or nothing". If it did develop Sky Lite, it would probably get its new set-top boxes certified by Freeview, so it wouldn't have to waste spectrum rebroadcasting its free-to-air channels.
Fellet said he was going off using the spectrum to launch a pay-television service for mobile phones because customers would need new phones with chips designed to receive the service. He had visited chip-maker Qualcomm in the United States to see how the technology might work, and while it was impressive he believed it had the worst economic case of any of the possible spectrum uses.
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.
