1.6 GHz fanout buffer with divider — what it buys the clock tree
The AD9514BCPZ-REEL7 is a 1:3 fanout buffer with an integrated divider, rated for clock inputs up to 1.6 GHz. That frequency ceiling covers the reference clocks for most high-speed ADCs, DACs, and FPGA transceivers; the divider lets you generate a lower-rate clock from the same source without a separate PLL or divider IC. Both input and output paths are fully differential, which means the part rejects common-mode noise on the clock line — a practical advantage when the trace runs past a switching regulator or a digital bus on a multi-layer board.
Output flexibility and supply tolerance
The three outputs can be independently configured as CMOS, LVDS, or LVPECL, so the same buffer can drive a CMOS FPGA input on one leg and an LVPECL ADC clock on another. Compared to the sibling AD9512BCPZ-REEL7, which tops out at 1.2 GHz and offers a 2:5 fanout, the AD9514BCPZ-REEL7 trades fanout count for higher frequency — a straight choice depending on whether you need more clock copies or a faster reference.
