onsemi MC100LVEP111MNRG

The MC100LVEP111 is a low skew 2:1:10 differential driver, designed with clock distribution in mind, accepting two clock sources into an input multiplexer. The PECL input signals can be either differential or single−ended (if the VBB output is used). HSTL inputs can be used when the LVEP111 is operating under PECL conditions. The LVEP111 specifically guarantees low output−to−output skew. Optimal design, layout, and processing minimize skew within a device and from device to device. To ensure tightest skew, both sides of differential outputs identically terminate into 50 Ω even if only one output is being used. If an output pair is unused, both outputs may be left open (unterminated) without affecting skew. The MC100LVEP111, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows the LVEP111 to be used for high performance clock distribution in +3.3 V or +2.5 V systems. Single−ended CLK input operation is limited to a VCC ≥ 3.0 V in PECL mode, or VEE ≤ -3.0 V in NECL mode when using VBB. Full operating range is available when using an external voltage reference. Designers can take advantage of the LVEP111’s performance to distribute low skew clocks across the backplane or the board.
