NBSG53A 2.5 V/3.3 V SiGe Selectable Differential Clock and Data D Flip-Flop/Clock Divider with Reset and OLS The NBSG53A is a multi-function differential D flip-flop (DFF) or fixed divide by two (DIV/2) clock generator.
This is a part of the GigaCommt family of high performance Silicon Germanium products.
A strappable control pin is provided to select between the two functions.
The device is housed in a low profile 4x4 mm 16-pin Flip-Chip BGA (FCBGA) or a 3x3 mm 16 pin QFN package.
