Both input and output paths are differential (Yes/Yes), preserving signal integrity over the multi-drop DDR2 bus where common-mode noise rejection matters. The 1.7 V to 1.9 V supply range aligns with the DDR2 memory controller and DIMM voltage rails, so no external level translation is needed between the driver and the DRAM clock inputs. Housed in a 52-VFBGA (4.5x7.0 mm CABGA), the fine-pitch BGA footprint demands a controlled-impedance PCB layout — the differential clock traces must be length-matched to within the driver's output-to-output skew budget to keep setup/hold margins on the DRAM side.","metaTitle":"Renesas CSPUA877ABVG SDRAM Clock Driver, 1:10, 410 MHz","metaDescription":"Renesas CSPUA877ABVG active-production SDRAM clock driver, 1:10 fanout, 410 MHz max, differential I/O, 52-VFBGA, RoHS3.
