Fanout clock buffers have lowest jitter

The LMK00334 and LMK00338 fanout buffers are intended for high-frequency, low-jitter clock/data distribution and level translation, with CML, LVPECL, LVDS, SSTL, HSTL, HCSL, or single-ended levels. They produce four and eight outputs, respectively, with ample jitter margin over the PCIe 3.0 specification – 30 fs RMS (typical) at 100 MHz.

The ICs have dual selectable inputs that operate up to 400 MHz and they feature a 75 db PSRR at 100 MHz. The industrial temperature range devices come in 5 x 5 and 6 x 6 mm WQFN packages at $1.20 or $1.80 ea/1,000.
