Active production — no end-of-life pressure
ADI lists the AD9508BCPZ as Active. ROHS3 compliant.
1.65 GHz fanout with integrated divider
The AD9508BCPZ accepts a single CMOS input and distributes it to four outputs — CMOS, HSTL, or LVDS. Maximum frequency hits 1.65 GHz, which covers the reference clock fanout for most high-speed ADCs, DACs, and FPGAs without needing a separate divider stage. The 1:4 ratio and differential I/O path keep additive jitter low — the divider is on-chip, so you avoid the jitter penalty of cascading a buffer and a divider from different families.
Supply voltage and temperature grade
Supply range is 2.375 V to 3.465 V, covering both 2.5 V and 3.3 V clock trees without a secondary LDO. Package is 24-LFCSP (4x4 mm) with an exposed pad.
Reel vs tray — AD9508BCPZ-REEL7 variant
The AD9508BCPZ-REEL7 is electrically identical — same output types, same 1.65 GHz ceiling, same supply range. The only difference is packaging: the -REEL7 suffix means tape-and-reel (7-inch reel), while the base AD9508BCPZ ships in a tray. If your pick-and-place line is set up for reeled parts, order the -REEL7 variant. For prototyping or low-volume builds, the tray version avoids the reel-up fee.
