Connor-Winfield's LM and PM Series are 5 x 7 mm surface mount, differential LVDS or LVPECL fixed frequency crystal controlled oscillators. The LM and PM Series clocks are designed for applications requiring quartz crystal stability, wide temperature range, low jitter and low power. Operating at 2.5 V or 3.3 V supply voltage, the LM Series provides LVDS differential outputs with enable/disable function while the PM Series provides LVPECL differential outputs. The low jitter frequency range of 25 to 670 MHz covers applications in SONET, GE, FC, G.709, OTU1, OTU2, 10GE copper and fiber, 10GEFC, SAS, HDVUSA, HDVEUR, and DDR clock rates. Additional features include: frequency stabilities as low as 20 ppm; low jitter 0.6 pS RMS typical; temperature ranges from -40° to 85°C.
