Hi，
I can't find the ip_clk frequency range for IFC interface of LS1021A in the spec such as datasheet, ARM and checklist. Could you please tell me it?
Thanks in advance!
Best regards!

There is no separately specified minimum/maximum frequency range for IFC ip_clk on LS1021A . ip_clk is the internal IFC module clock , equal to the processor’s platform clock ; it is not an interface pin clock. The datasheet explicitly says that IP_CLK is internal and unavailable on the interface pins.
For the standard LS1021A clock configuration:
The reference manual describes the platform PLL as generating a 300 MHz platform clock , and a documented RCW example uses SYSCLK = 100 MHz with SYS_PLL_RAT = 3 , producing ip_clk = 300 MHz .
