The GS9090 is a 270Mb/s reclocking deserializer with an internal FIFO. When used in conjunction with one of Gennum’s SDI Cable Equalizers, a receive solution for SD-SDI and DVB-ASI applications can be realized.
The Gennum GS9090 is a 270Mb/s reclocking deserializer designed for SMPTE 259M-C compliant descrambling and NRZI to NRZ decoding, as well as DVB-ASI sync word detection and 8b/10b decoding. When used with an SDI Cable Equalizer, it provides a receive solution for SD-SDI and DVB-ASI applications.
The device features an integrated line-based FIFO supporting four user-selectable modes for data alignment, delay, clock phase interchange, MPEG packet extraction, and ancillary data extraction. It includes an internal flywheel for noise-immune H, V, F extraction and offers automatic or manual selection between SMPTE video and DVB-ASI data processing.
| Data Rate | 270Mb/s |
|---|---|
| Core Power Supply | +1.8V |
| Typical Power Consumption | 145mW |
| Parallel Output Clock | 27MHz |
The PLL requires a +1.8V DC connection to its VDD pin.
The BUFF_GND pin must be connected directly to GND.
Setting this pin LOW causes the device to enter low-latency mode.
