... Data Sheet CLK_EXT Recommended Usage Analog Input The analog inputs to the CDK2308 is a switched capacitor track-and-hold amplifier optimized for differential opera- tion. Operation at common mode voltages at mid sup- ply is recommended even if performance will be good for the ranges specified. The CM_EXT pin provides a voltage suitable as common mode voltage reference ...

... Figure 6. Alternative Input Network Clock Input And Jitter Considerations Typically high-speed ADCs use both clock edges to generate internal timing signals. In the CDK2308 only the rising edge of the clock is used. Hence, input clock duty cycles between 20% and 80% is acceptable. The input clock can be supplied in a variety of formats. ...

... The digital outputs can be set in tristate mode by setting the OE_N signal high. ©2009 CADEKA Microcircuits LLC The CDK2308 employs digital offset correction. This means that the output code will be 4096 with the positive and negative inputs shorted together(zero differential). How- ever, small mismatches in parasitics at the input can cause this to alter slightly. The offset correction also results in ε ...
