NXP Semiconductors Clock Buffers, Drivers PCK111BD,151

The PCK111BD is a low voltage 1:10 differential clock driver designed for ECL, PECL, and HSTL applications. It features a typical part-to-part skew of 85 ps and an output-to-output skew of 20 ps, ensuring minimal delay variations across outputs. The device accepts two clock sources through an input multiplexer and can handle both differential and single-ended signals, utilizing a VBB output for reference. Operating within a voltage range of -2.25 V to -3.8 V for ECL and +2.375 V to +3.8 V for PECL, the PCK111BD is suitable for high-performance clock distribution in systems operating at +3.3 V or +2.5 V. It is packaged in a 32-lead LQFP format, making it compact for integration into various designs. The device is compatible with MC100EP111 in terms of form, fit, and function, and is specified to operate within an ambient temperature range of -40 °C to +85 °C. Proper termination of the differential outputs is necessary to maintain the specified skew performance.
