FemtoClock® Crystal-to-LVDS Frequency Synthesizer

The 844003BI-01 is a 3 differential output LVDS Synthesizer designed to generate Ethernet reference clock frequencies and is a member of the family of high performance clock solutions from IDT. Using a 19.53125MHz or 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated b ·Three differential LVDS output pairs on two banks, Bank A with one LVDS pair and Bank B with two LVDS output pairs\n·Using a 19.53125MHz or 25MHz crystal, the two output banks can be independently set for 625MHz, 312.5MHz, 156.25MHz or 125MHz\n·Selectable crystal oscillator interface or LVCMOS/LVTT;
