GS3470

The GS3470 is a multi-rate SDI Receiver which includes complete SMPTE processing. The SMPTE processing features can be bypassed to support signals with other coding schemes. Multi-link UHD can be supported when multiple GS3470 devices are used.
The device features a dual input buffer with a 2x2 MUX. The 2x2 MUX can select between either input for de-serialization and can route either of the two inputs to the serial loopback independently (reclocked or non-reclocked). In addition, the integrated Re-timer with an internal VCO provides a wide Input Jitter Tolerance (IJT).

提供可配置的断电模式，提高了灵活性。通过有选择地启用或禁用关键功能，每种断电模式都可以在不同程度上实现节能。断电模式下的可选项包括 CSR 访问、PCLK、重定时 SDO 环通输出和非重定时 SDO 环通输出。启用或禁用每个选项都将提供匹配应用需求的功耗级别。

本器件还有其他三种基本运行模式，包括：

• SMPTE 模式
• DVB-ASI mode
• Data-Through 模式

The GS3470 includes an audio de-embedder and audio clocks are internally generated. Up to eight channels (two audio groups) of serial digital audio may be extracted from the video data stream, in accordance with SMPTE ST 272-C and SMPTE ST 299.

与现有解决方案相比，其新功能和优势为：

• GS3470 has smaller package size, 9x9mm 100-ball BGA at 0.8mm ball pitch vs. GS2970A 11x11mm 100-ball BGA at 1mm ball pitch
• GS3470 has less power consumption, typical 220mW vs. GS2970A 350mW typical
• GS3470 fully supports 2K and multi-link UHD
• GS347x has two serial input ports and one internal 2x2 mux. The deserialized signal and the loop-through signal can be independently selected. GS2970A has only one serial input
• Eight configurable power-saving modes vs. GS2970A one standby mode
