1.1.1
64 kHz + 8 kHz Clock Extraction
The input data is shown in Figure 4. The 64 kHz clock signal consist of AMI code with 8 kHz Bipolar Violation.
Both the 64 kHz and 8 kHz components are extracted from the composite received signal and presented at the
64 kHz and 8 kHz output pins.
1.1.2
64 kHz + 8 kHz + 400 Hz Clock Extraction
Figure 4 shows the input data for this mode. The 64 kHz clock signal consist of AMI code with 8 kHz Bipolar
Violation removed every 400 Hz. The 64 kHz, 8 kHz and 400 Hz components are extracted from the composite
received signal and presented at the RClk, 8 kHz and 400 Hz output pins.
NOTE: The inputs are not aligned with all output signals. The above diagram is used to depict the output activity when the
input signals have errors.
