Clock Generators Suit Ethernet Apps
Thu, 08/06/2009 - 7:40am
Including an integrated crystal oscillator and PLL, the MAX3627 and MAX3629 from Maxim are clock generators with multiple LVDS and LVCMOS outputs. Ideal for Ethernet switches and routers, MAX3627 has 7 LVDS outputs and one LVCMOS output, while the MAX3629 has 5 LVDS outputs and three LVCMOS outputs. The clock generators feature a frequency of 312.5 MHz, clock signals of 0.14ps RMS from a 25 MHz crystal, and generate two pin-selectable frequencies for both Ethernet port clocking and MAC clocking.
