Renesas Electronics Clock Buffer 28-Pin VFQFPN Surface Mount 1.71-1.89V 1.2GHz Maximum Input Frequency 8P34S1208NBGI

Renesas Electronics 8P34S1208NBGI Clock Buffer 28-Pin VFQFPN is a surface mount semiconductor device designed for precision clock distribution applications in industrial and communications systems. This model operates reliably within a supply voltage range of 1.71V to 1.89V and supports maximum input frequencies of up to 1.2 GHz, making it ideal for high-speed synchronous circuits.

The device integrates two selectable differential inputs allowing flexible interfacing with LVDS or CML differential signals. Eight low skew outputs guarantee consistent timing across multiple loads, suitable for clock distribution networks requiring low jitter and low additive phase noise characteristics.

The built-in bias voltage reference aids interfacing with single-ended signals, enhancing design simplicity and signal stability. Its compact VFQFPN 28-pin surface mount package, measuring 5 mm in length and 0.8 mm in height, enables efficient PCB space utilization. The device supports operation between -40°C and 85°C, ensuring suitability in automotive and industrial environments despite the absence of specific automotive certifications.

Key specifications include a propagation delay time of 250 ps, which supports fast signal timing in time-critical applications. The surface mount VFQFPN package type facilitates automated assembly in high-volume production.

This clock buffer finds applications in telecommunications equipment, data communication systems, industrial electronics, and embedded system clock distribution requiring precise timing. It supports circuit designers in achieving low jitter and repeatable timing performance across outputs, essential in complex synchronous systems.

For PCB designers, complementary tools such as schematic symbols, footprints, and technical documents are available to assist in integration. Users can rely on Renesas Electronics’ reputation for quality semiconductor solutions in demanding environments.
