SN65LVDS105

The SN65LVDS105 from Texas Instruments is a versatile clock fanout buffer that implements the electrical characteristics of low-voltage differential signaling (LVDS). This device is designed to receive a single LVTTL input signal and distribute it to four LVDS outputs, making it suitable for high-speed clock distribution applications.

With a typical data signaling rate of up to 400 Mbps or clock frequencies up to 400 MHz, the SN65LVDS105 is ideal for systems requiring precise clock synchronization. It operates from a single 3.3-V supply and offers a low-voltage differential signaling output with a typical voltage of 350 mV into a 100-ohm load. The propagation delay is a mere 2.2 ns (typical), ensuring minimal skew in clock signals.

The device meets or exceeds the requirements of the ANSI EIA/TIA-644 standard for LVDS. The LVTTL inputs are 5-V tolerant, providing flexibility in interfacing with different logic levels. Driver outputs are high-impedance when disabled or when the supply voltage drops below 1.5 V. Bus-pin ESD protection exceeds 16 kV, enhancing robustness.

The SN65LVDS105 is available in SOIC and TSSOP packages, supporting various board space requirements. Its operating temperature range is from -40°C to 85°C, making it suitable for a wide range of industrial and commercial applications.
