The 8N0QV01KH-0208CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) from the FemtoClock NG series by Renesas Electronics. It utilizes fourth-generation technology to deliver high clock frequency and low phase noise performance. The device supports an output frequency range of 15.476MHz to 260MHz with a programming resolution of 435.9Hz divided by N. It features an I2C interface for reprogramming output frequencies, absolute pull-range (APR), and internal PLL control registers. The component operates on a 2.5V or 3.3V supply and is housed in a lead-free RoHS 6 compliant 10-lead ceramic package measuring 5mm x 7mm x 1.55mm.
This part belongs to the 8N0QV01 family of quad-frequency programmable VCXOs. The suffix 'KH' typically denotes specific power-up default frequencies and package variations within this series, while 'CDI8' indicates the ceramic package type and tape & reel shipping configuration. It is designed for applications requiring flexible frequency synthesis and precise jitter performance.
Direct replacements must match the 8N0QV01 family specifications, including the 10-lead ceramic package and I2C interface. Verify that substitute components support the required APR range and frequency resolution. Cross-reference pinouts and default frequency settings defined by FSEL0 and FSEL1 pins to ensure compatibility.
