ISL34341

WSVGA 24-Bit Long-Reach Video SERDES with Bi-directional Side-Channel

OVERVIEW

The ISL34341 is a serializer/deserializer of LVCMOS parallel video data. The video data presented to the serializer on the parallel LVCMOS bus is serialized into a high-speed differential signal. This differential signal is converted back to parallel video at the remote end by the deserializer. It also transports auxiliary data bi-directionally over the same link during the video vertical retrace interval.

I2 C bus mastering allows the placement of external slave devices on the remote side of the link. An I2 C controller can be placed on either side of the link allowing bi-directional I2 C communication through the link to the external devices on the other side. Both chips can be fully configured from a single controller or independently by local controllers.

KEY FEATURES

  • 24-bit RGB transport over single differential pair
  • 6MHz to 40MHz pixel clock rates
  • Bi-directional auxiliary data transport without extra bandwidth and over the same differential pair
  • I2C Bus Mastering to the remote side of the link with a controller on either the serializer or deserializer
  • 40MHz PCLK transports
  • SVGA 800x600 @ 70fps, 16% blanking
  • WSVGA 1024x600 @ 60fps, 8% blanking
  • Internal 100Ω termination on high-speed serial lines
  • DC balanced with industry standard 8b/10b line code allows AC-coupling
  • Provides immunity against ground shifts
  • Hot plugging with automatic resynchronization every line
  • 16 programmable settings each for transmitter amplitude boost and pre-emphasis and receiver equalization allow for longer cable lengths and higher data rates
  • Programmable power-down of the transmitter and the receiver
  • Same device for serializer and deserializer simplifies inventory
  • I2C communication interface
  • 8kV ESD rating for serial lines
  • Pb-free (RoHS compliant)
