CY7C0430BV CY7C0430CV Document #: 38-06027 Rev . *B Page 2 of 37 Functional Description The Quadport Datapath Switching Element (DSE) family offers four ports that may be clocked at independ ent frequencies from one another . Each port can read or write up to 133 MHz [1] , giving the device up to 10 Gb/s of data throughput.
CY7C0430BV CY7C0430CV Document #: 38-06027 Rev . *B Page 3 of 37 counter is loaded with an external address when the port’s Counter Load pin (CNTLD ) i s asserted LOW . When the port’s Counter Increment pin (CNTIN C ) is asserted, the addre ss counter will increment on each subsequent LOW-to- HIGH transition of that port’s clock signal.
