LMK03318RHST Description

Short technical summary and product information.

The LMK03318RHST from Texas Instruments is an ultra-low-noise clock generator designed for high-performance timing applications. It features a single fractional-N frequency synthesizer with an integrated VCO, providing flexible clock distribution and fanout capabilities.

This device offers up to 8 outputs with selectable types including CML, HCSL, LVCMOS, LVDS, and LVPECL. It operates with a core supply voltage of 3.3V and offers output supply voltages of 1.8V, 2.5V, or 3.3V. The maximum output frequency is 1GHz, with a typical jitter of 100-fs RMS for frequencies above 100 MHz.

Key features include I2C and pin-programmable configurations, dual inputs with automatic or manual selection, and frequency margining options. The operating temperature range is -40°C to 85°C. The device is housed in a 48-WQFN (7x7 mm) package suitable for surface mounting.

This clock generator is ideal for reducing BOM cost and board area by replacing multiple oscillators and clock distribution devices in systems requiring precise timing for multi-gigabit serial interfaces and digital devices.
