Clock targets optical, wireless network nodes

Clock targets optical, wireless network nodes

Developed for remote optical and wireless network nodes, cable infrastructure, and data communications equipment, the AD9548 clock generator/synchronizer IC enables system designers to use the standard, readily available and free 1-pps (pulse-per-second) signal of GPS satellite transmitters to generate and synchronize clock signals. The part includes a digital PLL that up-converts the 1-pps GPS signal while reducing input-time jitter or phase noise associated with the external references to as little as 300 fs.

The clock distribution section provides four output drivers. Each driver is programmable either as a single differential LVPECL/LVDS output or as pairs of single-ended CMOS outputs. ($24.82 ea/1,000 — available now.)
