Many programmable clock generators and power controllers use configuration files with alphanumeric codes. could be a firmware version for a specific clock device, stored in EEPROM. In this context, you would not find a datasheet for "CDCL008" — instead, it would be referenced in the programming guide of a parent IC.
The prefix "CDC" is famously associated with products. TI's "CDC" family includes clock generators, buffers, and jitter cleaners (e.g., CDCE906, CDCUN1208). Therefore, CDCL008 could logically be a variant of a low-jitter clock synthesizer or buffer. cdcl008
