CY27410 and CY27430 are both High performance Clock Generators and have 4 PLL. The CY27410 is Industrial grade device with 12 outputs (upto 8 Differential output pairs and 12 single ended) while the CY27430 is automotive grade device with 8 outputs (4 differential output pairs and 8 single ended). You can refer to the datasheet of the two devices for more information.
We have the CY3679 evaluation kit for CY27410 which can also be used to evaluate the performance of CY27430 device. The AC and DC characteristics remain same for the device.
