Operating Characteristics Notes:

1. With each data line loaded as, C = 50pf and R = 10k.

2. VOUT = 4.6V.

3. VOUT = 0.4V

4. Sink/Source currents  0.1mA.

5. Both Xtal and Xtal  4 Outputs.

6. With 50dB Signal/Noise Ratio.

7. See Figure 4, Bit Error Rate.

8. This Response Time is measured using a 10101010101.... 01 pattern input signal at a level of

230mVRMS (-2.3dB) with no noise.

9. Dependent upon Xtal tolerance.

10. The amplitude difference between the Transmit Output signals (tones) representing a logic ‘0’ a

logic ‘1’.
