Renesas Electronics Corporation Programmable Timers and Oscillators 8N3DV85AC-0180CDI

The 8N3DV85AC-0180CDI is a LVPECL Dual-Frequency Programmable VCXO from Quarktwin Technology Ltd., utilizing fourth generation FemtoClock® NG technology for high clock frequency and low phase noise performance. It operates with a supply voltage of either 2.5V or 3.3V and is housed in a compact 6-lead ceramic package measuring 5mm x 7mm x 1.55mm. This device can be factory-programmed to output two frequencies within the ranges of 15.476MHz to 866.67MHz and 975MHz to 1,300MHz, achieving a frequency precision of 218Hz or better. The VCXO pull range is programmable, typically from ±12.5 to ±787.5ppm, and it features a frequency selection pin (FSEL) compatible with LVCMOS/LVTTL levels. The device supports an extended operating temperature range of -40°C to 85°C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. RMS phase jitter is specified at 0.46ps (typical) at 622.08MHz for a bandwidth of 12kHz to 20MHz, and 0.47ps for 50kHz to 80MHz, indicating its suitability for high-performance timing applications.
