MC100LVEP111
2.5V / 3.3V 2:1:10
Differential ECL/PECL/HSTL
Clock Driver
Description
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 V_BB 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 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 when using VBB
(See Figure 11). Full operating range is available when using an external
voltage reference (See Figure 10). Designers can take advantage of the
LVEP111’s performance to distribute low skew clocks across the
backplane or the board.
