Description
The 8543 is a low skew, high performance 1-to-4 Differential-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS) the 8543 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100?. The 8543 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output and part-to-part skew characteristics make the 8543 ideal for those applications demanding well defined performance and repeatability.

Unable to debug RZ sample app on custom hardware
(Not sure if this post belongs here or in the RZ forum) I'm adapting the Renesas RZ RGA Sample app (R01AN2163EJ0210) to my custom hardware (built with a RZ/A1H chip). I have managed to import the DS-5 project into e2studio and build it successfully. I ...

ZOR Antenna shift resonnance frequency
Dear Sir or Madam, Currently we develop a first prototype of a new Bluetooth device. Therefore we used the example ZOR Antenna (document AN-B-027 Z, 5.4 ZOR Antenna, 1.6 mm Substrate). Attached you can see the Layerstack of our circuit board. Unfortunately the resonance frequency of ...

Retarget Keil5 project for DA14580 to DA14586
Hi, I have a Keil5 project for DA14580 target. The base for this project is ble_app_peripheral example from SDK 5.0.2.1 Now I want to retarget this project to DA14586, since that is the recommended part. What is the best way to do this? Thanks.
