Digital Fanout Buffers Fanout buffers convert one digital input signal into many logically-equivalent signals for signal distribution and for driving long lines. Unlike analog signal splitters, digital fanout buffers do not incur amplitude loss. Many models are available for distributing TTL, NECL, LVPECL, PECL, LVDS, and RS422 clock, data, and triggers

Digital Frequency Dividers Dividers receive a sinewave or digital - frequency f and output a synchronous digital frequency fln. AC- and DC- coupled frequency dividers are available in TTL, NECL, LVPECL, PECL logic families, with input rates up to 12 GHz and division ratios up to 4096. Multi- phase and programmable models provide tremendous flexibility.
