My customer request SI simulation model of CYUSB3304-68LTXI.

Please provide it if have.

Hello

In the above table, "SCL clock frequency" is divided by voltage. But, is this difference in voltage range correct with the recognition that "Internal regulator" and "single power supply 5 V required" are different?

Questions with Cy4609 development kit

1. Questions related to cypress HX3 Vendor Mode driver.

1.1 There is no hub function in this mode.

1.2 Does CyUSB.dll used by HX3 Blaster Plus have instructions for use? and it is best to have c++ code examples

2. Is there any source code for the firmware of Cy4609 HX3? we would like to develop some customized functions

Hope to answer.

thank you very much.

Hi. Cypess

customer want to test the USB3.0 eye pattern tes in the CYUSB3314-88LTXC?The CPU may generate the LFPS data singnal into upstearm, without any singnal  pass through in down stream. how to configurate this IC(HX3 Blaster Plus) or tell me the method HX3 eye pattern and device.(客户需要测试3314这个芯片的USB眼图，CPU能发出测试LFPS码型信号，经过HUB之后没有输出。如何配置才能测试出USB3.0波形，另外我们的芯片当初的眼图是使用了哪些设备进行测试的呢)？

thanks

1.Could you share the nominal voltage on the XTAL-OUT pin?

2. Any application note available for CY7C65642. if yes share the link also.

3. Port indicator has two modes mentioned in datasheet, that are manual and automatic. How to configure it?

4. What should be the drive condition of LED (Whether it is active low or high)

5. Pin 46 has three function GREEN[1]/SPI_SK/FIXED_PORT1 . i required Green LED function in that case what i have to do fixed port (non-removable).

6. Is it mandatory to configure non removable port? what is the purpose of the configuration.

Hello

Could you please share the the eye pattern for 2 downstream ports of CY7C65634-48AXC?

We have a custom board designed for use with the CYUSB3324 part. We are able to use the board as a hub, with the ID shorted to ground. If we hook the ID thru the 73.2Kohm to ground (Samsung tablet), there is no enumeration. I have read the data sheet and the app note KBA96321. The parts is strapped for internal ROM, with strapping as defined in the data sheet Table 6. VBUS_US is connected to 5V.

Hi Team,

1. Can you share IIH,IIL parameters of CY7C65642-48AXCT

2. Whether the VIH,VIL,VOH and VOL parameters are applicable for port indicator pin also (like amber, green)

3. For power consumption calculation, I am using internal LDO so VREG = 3.3V and VCC =5V.

Let consider no.of active downstream port = 2

Max. current = 78.6mA.

For worst case power calculation i have to take Vcc=5V

or Vreg=3.3V

When I use cy4609 development kit for product development, I can't find relevant codes and documents.

Is the operation method the same as FX product?

Thank you for your reading and help.

Hello

Q1) I think that it can be used by setting the interface to I2C. Please tell me the slave address when I2C is set.
Q2)  Does CY7C65634-48AXC support USB battery charging specification? If so, please let me know the revision.
