).
2. I
DD
requirement for Xtal/clock frequency of 2.24MHz.
3. Signal input level required to provide a constant autocorrelated output.
4. Measured with a 6.0kHz sinewave at the signal input.
5. Measured with V
DD
= 2.5 volts.
6. Measured with a 12kHz input signal.
7. Recommended input signal frequency range to correlation circuits.
8. Input (Signal In) to output (Output) time with a 2.24MHz Xtal/clock input.
