The 300 MHz clock rate means the data bus toggles on both edges, delivering an effective 600 MT/s per pin. For a networking packet buffer or a high-speed compute FIFO, that translates to a 1.8 GB/s peak bandwidth over the 18-bit data bus. The 1.7V to 1.9V core supply keeps I/O levels compatible with 1.8V logic families common in FPGA and ASIC designs.
165-ball BGA — layout considerations
The part comes in a 165-ball FBGA (13x15 mm) package. That is a fine-pitch BGA — expect 0.8 mm or 1.0 mm ball pitch depending on the specific ball map. The footprint requires controlled-impedance traces for the DDR data lines and adequate decoupling capacitance (typically 0.1 µF per supply pin plus bulk cap) within 5 mm of the package.
