Description
The 345 field programmable clock synthesizer generates up to nine high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal or clock input. It is designed to replace crystals and crystal oscillators in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 345 contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include eight selectable configuration registers, up to two sets of four low-skew outputs, and optional Spread Spectrum outputs. 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 345 is also available in factory programmed custom versions for high-volume applications.

DA14706 hibernation
Hi! I tried to run pmu_wakeup_demo from github.com/.../BLE_SDK10_DA1470x_examples on DA14706 DevKit. When I enable hibernation mode, power consumption decreases to 200 - 300 nA, and seems it is really hibernation. (It can't wake up by reset or power switching, only by ...

User board doesn't work with E2 Emulator connected
Hi, I am able to flash the firmware to the board RL78 MCU using E2 emulator. But my board doesn't work when the emulator still connected. If the E2 gets disconnected from the board then it works perfectly. Is there any way that makes the board working after flashing ...

EK-RA8M1 -- board no longer connects via J-Link, need help recovering
Hello, First of all, although I have 15+ years experience with STM32 devices, this is my first contact with Renesas products, so please bear with me. I recently bought an EK-RA8M1 board. I was able to generate a project for it, compile, flash, debug, receive data via SEGGER RTT ...
