8A34003ENBG

8A34003ENBG clock synchronizer IC 1GHz 4 48-WFQFN 

The 8A34003ENBG is a high-performance clock synchronizer IC from Renesas, housed in a 48-VFQFPN 7x7mm surface-mount package with exposed thermal pad, supporting a wide supply voltage range from 1.71V to 3.465V and stable operation across the full industrial temperature span of -40°C to 85°C for deployment in harsh outdoor and industrial operating scenarios. This integrated timing device embeds a high-precision PLL that detects and tracks the frequency and phase of input reference signals, converts them into ultra-stable output clocks, and supports frequency conversion and signal synchronization to eliminate timing drift caused by transmission path fluctuations.

It features 4 independent output channels with 2:4 input-to-output ratio, fully differential input and output interfaces, and supports multiple industry-standard signal formats including CML, HCSL, HSTL, LVCMOS, LVDS, LVPECL and SSTL, with a maximum output frequency reaching 1GHz to meet diverse high-speed system timing requirements. It is widely deployed in computer chips, digital circuits, radio communication systems, audio and video equipment and high-speed network infrastructure, acting as the core timing foundation to guarantee stable data transmission and processing.
