Renesas Electronics Corporation Programmable Timers and Oscillators 8N4DV85EC-0015CDI

The IDT8N4DV85 is a dual-frequency programmable voltage-controlled crystal oscillator (VCXO) designed for high precision and low phase noise applications. It operates within a frequency range of 15.476MHz to 866.67MHz and 975MHz to 1300MHz, with a programming resolution of 218Hz or better. The device utilizes fourth generation FemtoClock¬Æ NG technology, ensuring optimal clock frequency performance. This VCXO can be powered by either a 2.5V or 3.3V supply and is housed in a compact 6-lead ceramic package measuring 5mm x 7mm x 1.55mm. It features a differential LVDS clock output and includes an output enable control input compatible with LVCMOS/LVTTL levels. The device supports an ambient operating temperature range of -40¬8C to 85¬8C, making it suitable for various applications in wireless infrastructure, telecommunications, and networking equipment. The IDT8N4DV85 can be factory-programmed to two specific frequencies, selected via the FSEL pin, and offers an absolute pull range programmable from ¬±4.5 to ¬±754.5ppm. The device's low RMS phase jitter of 0.47ps at 156.25MHz enhances its performance in timing-critical applications.
