Applications
TW2826
Features
TW2826 is a record multiplexer that converts multiple
D1 video inputs into quad CIF format for multi-channel
DVR applications. The maximum number of D1 video
that can be accepted is 16. The output can be
selected from any D1 video or quad CIF video.
Description
This product accepts multiple channels BT.656
compliant video data in byte interleaving format,
processes them and outputs them in either its original
size or in quad CIF size based on user control. The
output will be in BT.656 byte interleaving format in
the case of multi-channel output.
Four BT.656 Compliant Input
Maximum Input Rate of 108 MHz with
Byte-Interleaved Format Support
Four BT.656 Compliant Output Ports
Up to 108 MHz Byte-Interleave Output Support
Channel ID Support
User Selectable D1 or Quad CIF Output
Single SDRAM 16 Bits @166MHz
Optional GPIO
Miscellaneous
1.8/3.3V Operation Voltage
Supports 2-wire Serial Bus Interface
144 Ld LQFP Package
