A clock signal is required for operation. The clock signal is applied to the CLK pin at 4.096MHz. As with many precision data converters, a low-jitter clock is required to achieve data sheet performance. Avoid the use of R-C clock oscillators. A crystal-based clock source is recommended. Avoid ringing on the clock signal by placing a series resistor in the clock PCB trace to source-terminate. Keep the clock signal routed away from other clock signals, input pins, and analog components.
