Renesas Electronics Corporation Programmable Timers and Oscillators 8N4DV85EC-0089CDI

The 8N4DV85EC-0089CDI is a dual-frequency programmable voltage-controlled crystal oscillator (VCXO) from Quarktwin Technology Ltd. It utilizes fourth generation FemtoClock¬Æ NG technology, offering high clock frequency and low phase noise performance. The device can be programmed to output two frequencies within the ranges of 15.476MHz to 866.67MHz and 975MHz to 1300MHz, with a frequency precision of 218Hz or better. It operates on a supply voltage of either 2.5V or 3.3V and is housed in a compact, lead-free 6-lead ceramic package measuring 5mm x 7mm x 1.55mm. The VCXO features an absolute pull range (APR) that can be programmed from ¬±4.5 to ¬±754.5ppm, making it suitable for various applications in wireless infrastructure, telecommunications, and networking equipment. The device also includes a differential LVDS clock output and an output enable control input compatible with LVCMOS/LVTTL levels. It operates over an extended temperature range of -40¬8C to 85¬8C, ensuring reliability in diverse environmental conditions. The low RMS phase jitter of 0.47ps at 156.25MHz enhances its performance in timing applications.
