NB6L295 2.5V / 3.3V Dual Channel Programmable Clock/Data Delay with Differential LVPECL Outputs
Product Overview
The NB6L295 is a versatile Dual Channel Programmable Delay Chip designed for precise clock or data de-skewing and timing adjustment. It offers two independent, configurable delay channels (PD0 and PD1) that can operate in either Dual Delay Mode or Extended Delay Mode. In Dual Delay Mode, each channel provides independent programmable delay. In Extended Delay Mode, the channels are cascaded for additive delay. Programming is achieved via a 3-pin Serial Data Interface, allowing for fine-grained delay adjustments with resolutions typically as low as 11 ps. The device supports multi-level inputs compatible with LVPECL, LVDS, CML, LVCMOS, and LVTTL logic levels, and features differential LVPECL outputs. This chip is ideal for applications requiring precise timing control and de-skewing in high-speed digital systems.
