CY28352 Description
This PLL clock buffer is designed for 2.5-VDD and 2.5-AVDD operation and differential output levels. This device is a zero delay buffer that distributes a clock input CLKIN to six differential pairs of clock outputs (CLKT[0:5], CLKC[0:5]) and one feedback clock output FBOUT. The clock outputs are controlled by the input clock CLKIN and the feedback clock FBIN.
CY28352 Key Features
- Supports 333-MHz and 400-MHz DDR SDRAM
- 200-MHz operating frequency
- Phase-locked loop (PLL) clock distribution for double data rate synchronous DRAM
CY28352 Applications
- Distributes one clock input to six differential outputs
- External feedback pin FBIN is used to synchronize output to clock input
- Conforms to DDRI specification
- Spread Aware™ for electromagnetic interference (EMI) reduction
