Hi3136 support is a DVB-S (ETS 300 421), standard satellite channel digital television receiver chip DVB-S2 (ETS 302 307) and DirecTV (ITU-R BO.1294 System B). Chip to complete the satellite signal from the digital baseband samples to digital processing of the output MPEG-TS stream. In DVB-S2 aspect, chip supports QPSK, 8PSK, 16APSK and 32APSK mode, support all bit rates from 1/4 to 9/10, the CCM support, support for long frames and short frames, and in particular to support the VCM ACM function, and supports TS and generic stream (GS) process, is the industry's most complete product, greatly expands the application areas.
Hi3136 supports symbol rates as low as 1MSps, symbol rate QPSK and 8PSK support up to 60MSps, symbol rate support of up to 16APSK 47MSps, symbol rate support of up to 32APSK 37.5MSps, support a variety of services from very low speed to ultra-high speed .
Hi3136 fast and highly reliable blind scan function, a program can achieve full-band search, automatically receive frequency, symbol rate and code rate information. Provides superior anti-phase noise, multipath and interference, the carrier frequency acquisition range, the ability to adapt to the environment.
Hi3136 CPU using an I2C interface to interact with real-time monitoring the signal strength, bit error rate and signal quality, user-adjust the antenna search star. Hi3136 supports DiSEqC 2.X protocol, and supports FSK protocol for easy connection with various satellite equipment. Hi3136 supports serial and parallel TS stream output interface, the line-sequential signal can be flexibly configured for easy PCB routing. Hi3136 external circuit is simple, two-layer support board traces, BOM cost reduction.
Hi3136 properties
