On the PC you open the 'CDCE9XX Programmer GUI' that I've written (see below). You also need to connect the programmer with the DFO through 4 wires. It is connected to your PCB with a Mini USB cable. To program the CDCE913 on the DFO PCB you will need a programmer hardware called 'CDCE9XX Programmer' (see below). The register values can be saved into an Intel Hex file. Clock Pro will then automatically calculate the register values for your configuration. With Clock Pro you can create a setup for the CDCE913 IC by specifying the desired frequencies.

The first step is use the Clock Pro software by Texas Instruments. This pic shows the required hard- and software to successfully program the DFO: By tying the s0 input of the CDCE913 to either a low or a high logic level, it's possible to change the frequency of the clock output signal. It can be programmed to output clock signals with (almost) any desired frequencies between 0.8 and 230 MHz. The CDCE913 on the dual frequency oscillator (DFO) has an built-in PLL (phase-locked loop). I've designed such an oscillator using the CDCE913 clock generation ICs by Texas Instruments (CDCE925 in the previous design). So to restore compatibility with the Framemeister for both 50 and 60 Hz modes, we need an oscillator with two different frequencies to choose from. This is a known issue, also mentioned in the Framemeister Wiki: But with modern devices like the X-RGB Mini Framemeister this can and will cause problems. Back in the days this hardly was a problem because CRT TVs are quite tolerant regarding the output rate. A PAL Megadrive running on 60 Hz has a slightly different picture output rate than a genuine NTSC console. PAL: 53.203424 MHz (= 12 x PAL subcarrier 4.3361875 MHz)īecause all other timings are derived from this master clock, it's easy to see what's the problem. You can see the different oscillator frequencies in PAL and NTSC consoles. Here's a little excerpt from the Megadrive 2 schematics: The reason why these PAL consoles work fine on 50 Hz but don't on 60 Hz is that PAL and NTSC consoles use oscillators/crystals with different frequencies. It just wasn't fun to play the games this way. Switching my PAL Megadrive 2 to 60 Hz or using NTSC games on my PAL PSX introduced massive stuttering, messed up black levels and other picture problems. I quickly found out that my modded consoles don't work well with the Framemeister. Some months ago I got a X-RGB Mini device, also known as Framemeister. Something not related to videogame controllers for a change.Ī programmable oscillator that let you switch between two different frequencies
