Description
The 542 is cost effective way to produce a high-quality clock output divided from a clock input. The chip accepts a clock input up to 156 MHz at 3.3 V and produces a divide by 2, 4, 6, 8, 12, or 16 of the input clock. There are two outputs on the chip, one being a low-skew divide by two of the other. For instance, if an 100 MHz input clock is used, the 542 can produce low-skew 50 MHz and 25 MHz clocks, or low skew 25 MHz and 12.5 MHz clocks. The chip has an all-chip power-down mode that stops the outputs low, and an OE pin that tri-states the outputs. See the 501, 502, 511, 512, and 525 for clock multipliers.

Recommendation or direct replacement for the 542MLFT
We have an old design that used the 542MLFT and I see that this device is obsolete.What do you recommend we use to replace this on new designs? [locked by: Sai (SWF) at 13:33 (GMT 0) on 16 Jun 2022]

DA16200 Iperf - Cannot exceed and average bandwidth of 27 Mbps over UDP
Hello, I am currently working with DA16200 (SparkFun Qwiic WiFi Shield) and performing some "iperf" tests. I flashed the DA16200 FreeRTOS SDK example and configured it as an access point. I installed iperf v2.2.1 on my PC and connected to the access point. I configured the access point ...

DA14592 Proper TRNG and DRBG usage for single value.
I have need to call rand() at startup of a firmware I'm creating. First attempt it seems was generating the same value each boot. So.. I enabled: #define dg_configUSE_SYS_DRBG (1)#define dg_configUSE_SYS_TRNG (1) After this, I get a random value as ...
