Hello

Starting from a 24Mhz crystal I need an output on the same frequency but with vcxo capability.

May I use a CY22800  or do I need a CY22801 ?

I though that with CY36800 InstaClock could be possible to configure all the features of the chips, but reading

this post "http://www.cypress.com/forum/programmable-clocks/instaclock-genius-effort" seems different.

Becouse the CY36800 kit is not currently available on short time, there is a document with the protocol for programming the chips?

Hi,

I'm exploring using the CY23FS04 to allow optional system synchronization with an external clock.  I've had trouble finding any off-the-shelf pullable crystals.  For a 100MHz system clock, I'd need a 16.667 MHz crystal.  If I used the CY23FS08, I could also use a 12.500 or 25.000 MHz crystal.  Does anyone know of an OTS source for pullable crystals at one of these frequencies?

Thanks,

Hello,

I am keep getting an error on the last step of the instaclock software. On step 5(Plug programmer and program device), somehow my computer is not detecting my board, and it's saying "connect your Titanium board". I don't know why this is the case, and I am really getting annoyed by this error, so I would very much appreciate help/guidance.

Thanks

I'm looking for a reference design/schematic for the CY22800 clock generator.

Couldn't find anything on the Cypress website.

I created a new case for this, but wanted to try the forum also.

Any suggestions anyone?

Thanks!

 I am looking for the .pkg file for the CY2309 IBS model. Does anyone have it or know where I can find it?

Thanks,

I know these are optimized for 25Mhz in and 100Mhz out.  But, is it possible to use a 24Mhz in to get 96Mhz out?

Thanks,

 As the subject states, I am interested in changing the 24 MHz crystal on my PSoC5LP development board to and 18.5 MHz crystal.  Will this cause me any problems or can I just swap it and go?

 I'm a student and I'm still trying to figure out what's going on here and how to use everything.

I'm trying to make a pulse oximeter, but I'm still in the preliminary steps. My goal at this point is to have 2 PWM's offset by 180degrees. In otherwords, I want one to turn on as the other's turning off and vice versa. 

I've tried messing with the clock settings (standard clocks) but VC3 is the only clock that actually has my PWM pulse.

So far, what I have is really simple, just 2 led's that I'm pulsing using PWM16 with reasonably long periods, and I can make 2 things happen, I can make them both pulse at the same time, by using VC3, and if I hook PWM16_2 up to say VC2 or VC1 for that matter, there's a delay, and then it just stays on and never shuts back off.

So my simplified question is this: is there a way I can assign VC* = VC3 + Period/2 ? 

Or am I going about this wrongly? 

I'd like to avoid ADC for this portion if I can, simply because I'm not familiar with it.

Thanks in advance,

Tyler

I've inherited a design from an engineer that has since left my company that uses a CY2545 clock generator. I should be able to program this device via the I2C bus, but I can't find any documentation about programming this device.

The device isn't supported by CyClocks, CyClocks RT or Robo Clock either!

Does anybody have some familiarity with theis device or have any advice on how to program this device?

Thanks,

Hello all,

I am new to this forum and cypress IC.

I want to use DMA for caputuring 80 bits data from ADC at a speed of 8MHz.

can you guide me the maximum speed and clock frequency for DMA used and the procedure to use DMA?

Please reply

regards,

PZ
