Ppm clk
WebMay 25, 2024 · A reasonably good computer clock crystal has a stability of 100 parts per million (ppm). This equates to a drift of 1 second in every 10,000 seconds, or roughly 5 minutes per month. So, two computers set to the correct time at the start of a month could differ significantly at the end of the month. Many PC clocks are far worse. WebSince the nominal reference clock period is 8 ns, 100 ppm is 0.0008 ns. This is 0.0008 * 232 subnanoseconds, which equals approximately 3435974 subnanoseconds (0x346DC6). 2. …

WebAug 3, 2012 · 13. Here's how I've connected the AD9850 module up and a simple Python program to show how to set the frequency to 1000Hz. The AD9850 needs to run at 5V to work properly with the 125MHz crystal. It would probably be ok to wire 4 GPIO pins directly to the module since they are just inputs, but connecting via a MCP23017 effectively turns … Web±5 ~ ±50 ppm: Search. Our Products.

WebClock (SPI CLK, SCLK) Chip select (CS) main out, subnode in (MOSI) main in, subnode out (MISO) The device that generates the clock signal is called the main. Data transmitted between the main and the subnode is synchronized to the clock generated by the main. SPI devices support much higher clock frequencies compared to I 2 C interfaces.
