RDX004M4 10 Bit 4 GHz 1:4 Demultiplexer Features 10 Bit Differential Input 4 GHz Operating Frequency Selectable 1:4, 1:2, 1:1 Mode Staggered or Simultaneous Output Grey to Binary Converter Selectable DDR clock Reset for multiple device synchronization Pseudo Random Pattern Generator LVDS Compatible Output Latency of 3 to 9 Clocks Depending on Operating Mode 6 W Power Dissipation BGA package Companion Chip for RAD004 Product Description The RDX004M4 was developed as an output demultiplexer for the Teledyne Scientific family of analog to digital converters. Four control signals are used to select features and device operation mode. BIN enables the grey to binary converter. DS0 and DS1 select the demultiplexer mode. It can operate in 1:4, 1:2, and direct mode 1:1. When in demultiplexer mode STAG selects the staggered or simultaneous output. Although the RDX004M4 was developed as a companion chip for the Teledyne Scientific analog to digital converters, it can also be used as a generic demultiplexer. For this application the grey to binary converter can be disabled reducing the power dissipation.
