#CROSSLINK Series #CROSSLINK vs XO3L

Overall, XO3L offers greater flexibility and is more akin to a general-purpose CPLD; CROSSLINK is more specialized.

For the requirement of converting subLVDS to MIPI, CROSSLINK has an advantage due to its higher integration, leading to greater stability.

#Key Points #CrossLink does not support JTAG download, requiring a separate download cable.

#IO Power-up Voltage IOs are low before program loading, or at least interpreted as low by the control logic.

#NVCM One-Time Programming (OTP)

If this one opportunity is used to configure the device to boot primarily from NVCM, subsequent operations will be limited to on-line debugging, and modifications to IO configurations will no longer take effect.

#Download Options

The actual flash used is MX25L1606EM1I-12G, but the options shown above are supported.

#Dual-Boot EXT-EXT External dual-boot method

#Internal Oscillator Can generate low-frequency LFCLKOUT=10KHz and one of the high-frequency HFCLKOUT options: 48M, 24M, 12M, or 6M, controlled by a division factor.

Use the following code for invocation, with the HFCLKDIV parameter for frequency division settings, and HFOUTEN: 1 to enable:

#Peripheral Clock Divider There are 4 dividers (2 in bank1, 2 in bank2) which can divide external input clocks by factors of 2, 3.5, 4, 7, and 8. The invocation code is as follows:

If using the dividers can meet the requirements, PLL resources can be saved.
