We have an old design that used the 542MLFT and I see that this device is obsolete.What do you recommend we use to replace this on new designs?
The Product page is here for the old 542 device that is obsolete: https://www.renesas.com/us/en/products/clocks-timing/clock-distribution/clock-buffers-drivers/542-clock-divider

We don't mention a direct drop-in replacement but for a new design we would recommend the 5P35023 is a programmable part that can divide the input clock by two.
