Description
The 280 field programmable spread spectrum clock synthesizer generates up to four high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals, crystal oscillators and stand alone spread spectrum devices in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 280 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include input/output frequencies, spread spectrum amount and eight selectable configuration registers. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The 280 is also available in factory programmed custom versions for high-volume applications.

Unable to Flash 280KB HEX File on EK-RA8M1 – Fails with 'Failed to Erase Sectors' Error, Smaller size hex files Work Fine
I am facing an issue while flashing a hex file of around 280KB to my Renesas EK-RA8M1 board. When the file size was around 70KB, I was able to flash it without any problems. However, with the larger file, the flashing process fails, and I get the following error ...

SLG46620V emulating and programming fine, behaves unusually in circuit.
I'm not really sure how else to describe it, the SLG46620Vs I have been programming work fine when being emulated and when testing in a breadboard, when I go to actually solder one on a board, however, it begins to behave erratically. I've gone through at least 4 ...

Can we add a drain wire from the lid to ground on your rad hard parts?
... we add a drain wire from the lid to our analog ground? Answer: The lids are sealed using a solder with a melting temperature of 280 degrees C. If you can stay well below this temperature and the part is not powered up, you should be able to tack solder ...
