Overview
The NB6L295M, produced by onsemi, is a Dual Channel Programmable Delay Chip designed primarily for clock or data de-skewing and timing adjustment. This device is part of the ECLinPS MAX™ family of high-performance products. It features two individual variable delay channels, PD0 and PD1, which can be configured in either Dual Delay or Extended Delay modes. The NB6L295M supports multi-level inputs compatible with differential LVPECL, LVDS, or CML logic levels, as well as single-ended LVPECL, LVCMOS, or LVTTL. The device is packaged in a 4 mm x 4 mm 24-pin QFN Pb-free package and operates over an ambient temperature range of -40°C to 85°C.
