概览

The GS1660A is a multi-rate SDI Receiver which includes complete SMPTE processing, as per 292M and SMPTE 259M-C. The SMPTE processing features can be bypassed to support signals with other coding schemes.

The device features an integrated Reclocker with an internal VCO and a wide Input Jitter Tolerance (IJT) of 0.7UI.

A serial digital loop through output is provided, which can be configured to output either reclocked or non-reclocked serial digital data. The Serial Digital Output can be connected to an external Cable Driver.

The device operates in one of four basic modes: SMPTE mode, DVB-ASI mode, Data-Through mode or Standby mode. 

In SMPTE mode, the GS1660A performs SMPTE de-scrambling and NRZI to NRZ decoding and word alignment. Line-based CRC errors, line number errors, TRS errors and ancillary data check sum errors can all be detected. The GS1660A also provides ancillary data extraction. The entire ancillary data packet is extracted, and written to host-accessible registers. Other processing functions include H:V:F timing extraction, Luma and Chroma ancillary data indication, video standard detection, and SMPTE 352M packet detection and decoding. All of the processing features are optional and may be enabled or disabled via the Host Interface.

在 DVB-ASI 模式中,将 8b/10b 解码应用至接收到的数据流。

在 Data-Through 模式下,将禁用所有形式的 SMPTE 和 DVB-ASI 解码,器件可用作简单的串联-并联转换器。

The device can also be placed in a lower power Standby mode. In this mode, no signal processing is carried out and the parallel output is held static.

Parallel data outputs are provided in 20-bit or 10-bit multiplexed format for HD and SD video rates. The associated Parallel Clock input signal operates at 148.5 or 148.5/1.001MHz (HD 10-bit multiplexed modes), 74.25 or 74.25/1.001MHz (for HD 20-bit mode), 27MHz (for SD 10-bit mode) and 13.5MHz (for SD 20-bit mode).
