ZL30151

The ZL30151 is a high performance line card device in a tiny 5x5mm package. The device accepts up to 3 input references and generates up to 3 differential or 6 single-ended CMOS output clocks with ultra-low jitter performance of 250fs RMS. An integrated digital phase locked loop (DPLL) with programmable loop bandwidth down to 1Hz provides hitless reference switching, holdover and jitter filtering. An integrated fractional-N analog PLL (APLL) generates ultra-low jitter output clocks programmable to any frequency between <1Hz to 650MHz.

The ZL30151 has all required features and functions to serve as a line card timing IC in a wide variety of equipment types.
