The LVPECL differential output swings fast enough to drive 74.25 MHz into a terminated line — common in video clocking, FPGA reference clocks, and SerDes reference paths where edge jitter matters more than absolute frequency.
Housed in a 5.00 mm × 3.20 mm no-lead package, seated height 0.90 mm max — a standard footprint that reflows with a typical lead-free profile and does not require via-in-pad.
±25 ppm across the -40 to +85 °C operating range.
