Renesas Electronics Corporation Programmable Timers and Oscillators 8N4DV85BC-0105CDI

The 8N4DV85BC-0105CDI 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 and telecommunications. The device also includes an output enable control input that is compatible with LVCMOS/LVTTL levels, and it operates over an extended temperature range of -40¬8C to 85¬8C. The typical RMS phase jitter at 156.25MHz is 0.47ps, indicating its suitability for high-performance timing applications.
