MC100LVEP111
2.5V /
3.3V 1:10 Differential ECL/PECL/HSTL Clock Driver
Description
The MC100L VEP111 is a low skew 1−to−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 V BB output is used). HSTL inputs can be used when the L VEP111 is operating under PECL conditions.
The L VEP111 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 W 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 V CC 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 V CC≥3.0 V in PECL mode, or V EE v−3.0 V in NECL mode. Designers can take advantage of the L VEP111’s performance to distribute low skew clocks across the backplane or the board. In a PECL environment, series or Thevenin line terminations are typically used as they require no additional power supplies. For more information on using PECL, designers should refer to Application Note AN1406/D.
