8N4QV01LG-1155CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4QV01LG-1155CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) utilizing fourth-generation FemtoClock NG technology. It operates within a supply voltage range of 3.135V to 3.465V and draws 160mA. The device provides four power-up default frequencies, including 150MHz, 156.25MHz, 212.5MHz, and 150MHz, which are reprogrammable via an I2C interface with a resolution of 435.9Hz ÷N. It features an LVDS differential clock output and supports an absolute pull-range (APR) from ±4.5ppm to ±754.5ppm. The component is housed in a 10-CLCC package and functions across an ambient temperature range of -40°C to 85°C.
