<SamsungRONG> CE 6353 DVB-T解调器
The 中电® CE 6353 DVB-T demodulator meets the performance requirements of NorDig Unifi ed 1.0.2
standard. The device includes a high-performance 10-bit A/D converter capable of accepting direct
IF integrated digital fi ltering and requires only a single 8 MHz channel SAW fi lter for 6, 7 and 8MHz COFDM signal reception, plus a 7-bit IntelC 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 demodulator also features excellent single-frequency network SFN performance,unique auto active impulse noise fi ltering and very low power consumption, including software/hardware power-down mode.
Terrestrial Receiver Application
Intel supports the Intel CE 6353 demodulator with four reference designs from can tuner1 manufacturers
Panasonic, Philips, AD 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 onsumption.
The Intel CE 6353 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 incorporates a two-wire bus “bypass mode,” enabling direct unrestricted programming of the tuner.
The Intel CE 6353 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 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 fi lter. Driven by high-level commands and featuring full automation, the Intel CE 6353 demodulator can be directly interfaced in parallel or serial modes to all standard MPEG-2 processing chips.
