The user has two options to supply the VIP 15.36-MHz input clock:
• via a standard 15.36-MHz crystal or
• via an external source, e.g. connecting the DELIC output pin L1_CLK (duty cycle of
Note: It is recommended to supply the VIP 15.36-MHz input clock via the DELIC.
In case a crystal (serial resonance) is connected, it should meet the requirements shown
