Figure 20. Driving the Clock From an Impedance Matched Source
The clock signals, CLK+ and CLK–, should be well matched and must both be driven.
A transformer ensures minimal skew between the two complementary channels. However, skew levels of up
to 500 ps between CLK+ and CLK– can be tolerated with some performance degradation.
The clock input can also be driven differentially with a 5-V TTL signal by using an RF transformer to convert the
TTL signal to a differential signal. The TTL signal is ac-coupled to the positive primary terminal with a high pass
circuit. The negative terminal of the transformer is connected to ground (see Figure 21). The transformer
secondary is connected to the CLK inputs.
