The Evertz 500DA Reclocking Distribution Amplifier provides inexpensive distribution of your SMPTE ST 310 and SMPTE ST 259 serial digital video signal at rates of 19.4Mb/s and 143Mb/s to 540Mb/s. Ideal in applications where a large quantity of outputs are required, the DA features an auto-equalized input with nine isolated reclocked outputs. The input also features an isolated return that is capacitively coupled to ground.
The 500DA has been designed for use as a SMPTE ST 310 (19.4Mb/s), DVB-ASI or SMPTE ST 259 distribution product. SMPTE ST 310 support is selected by setting a rate select jumper.
The 500DA is housed in the 3RU 500FR Exponent frame that will hold up to 16 modules.
特点
- 用于SMPTE ST 259 (143 到540Mb/s) 或DVB/ASI 信号的正常模式 - 自动检测正确的速率
- 跳线选择模式，用于SMPTE ST 310 (19.4Mb/s)
- 完全前面板热插拔而不需断开BNC
- 独立分离的输出驱动器，保证了没有跨通道影响(如：不需要终止没用的输出)
- 输出保持了从输入到输出的极性，用于DVB-ASI 应用中
- 当输入信号丢失时，记录输出在主机状态总线上用作质量监视
