• Manufacturer Part Number: pef20550
• Description: Extended Line Card Interface Controller Elic
• Manufacturer: Infineon Technologies Corporation

Figure 68 shows the relationship between the DCL input and the generated RCL for the
different prescaler divisors in case CMD1:CSS = 1:
Figure 68
Clock Signal Timing for the Different Prescaler Divisors if CMD1:CSS = 1
CFI Clock Output Rate CMD2:COC
This feature applies only if the configurable interface is clocked and synchronized via the
PCM interface clock and framing signals (PDC, PFS), i.e. if CMD1:CSS = 0.
In this case the ELIC delivers an output clock signal at pin DCL with a frequency identical
to or double the selected CFI data rate:
For CMD2:COC = 0, the frequency of DCL is identical to the CFI data rate
For CMD2:COC = 1, the frequency of DCL is twice the CFI data rate
