8N3QV01LG-0020CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N3QV01LG-0020CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) utilizing FemtoClock NG technology. It operates on a 2.5V or 3.3V supply with a current draw of 145 mA. The device provides four power-up default frequencies, including 125 MHz, 100 MHz, 122.88 MHz, and 156.25 MHz, which are reprogrammable via an I2C interface. It features LVCMOS/LVTTL compatible control inputs and supports an absolute pull-range (APR) from ±2.5 to ±727.5 ppm. The component is housed in a 10-CLCC package and functions within an ambient operating temperature range of -40°C to 85°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix '0020' against official documentation to confirm the exact set of four default power-up frequencies. Confirm that the 10-CLCC package variant matches the design requirements. Check for any product change notices (PCN) regarding manufacturing updates. Ensure the I2C interface compatibility aligns with the system controller. Validate the supply voltage mode (2.5V vs 3.3V) settings during integration.

Programmable Timers And Oscillators Selection Notes

Select this component when low phase jitter and flexible frequency pulling are required for clock generation. The I2C interface allows for dynamic frequency adjustment post-production. Verify that the required output frequencies fall within the supported range of 15.476 MHz to 260 MHz. Ensure the system can accommodate the 145 mA supply current. Confirm that the 10-CLCC package dimensions fit the PCB layout constraints.
