Key Features
- High-performance 1:8 LVCMOS clock buffer with very low output skew (< 55 ps) and extremely low additive jitter (< 25 fs nominal).
- Modular design with pin compatibility across different fan-out variations (1:2, 1:3, 1:4, 1:6, and 1:8).
- Synchronous output enable control (1G) to switch outputs into a low state when 1G is low.
- Fail-safe input to prevent oscillation at the outputs in the absence of an input signal and allows for input signals before VDD is supplied.
- Wide operating temperature range from –40°C to 125°C.
