2.5V / 3.3V 1:10 Differential

ECL/PECL/HSTL Clock Driver

Description

The MC100LVEP111 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

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

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

LVEP111 to be used for high performance clock distribution in +3.3 V or

(See Figure 10). Full operating range is available when using an external

voltage reference (See Figure 9). Designers can take advantage of the

LVEP111’s performance to distribute low skew clocks across the

backplane or the board.
