The MC100LVE222 is a low skew 1:15 differential ÷1/÷2 ECL

fanout buffer designed with clock distribution in mind. The

LVECL/LVPECL input signal pairs can be differential or used

single–ended (with VBB output reference bypassed and connected to

the unused input of a pair). Either of two fully differential clock inputs

may be selected. Each of the four output banks of 2, 3, 4, and 6

differential pairs may be independently configured to fanout 1X or

1/2X of the input frequency. The LVE222 specifically guarantees low

output to output skew. Optimal design, layout, and processing

minimize skew within a device and from lot to lot.

CASE 848D

The fsel pins and CLK_Sel pin are asynchronous control inputs.

Any changes may cause indeterminate output states requiring a MR

pulse to resynchronize any 1/2X outputs.

MARKING DIAGRAM*

To ensure that the tight skew specification is realized, both sides of

any differential output pair need to be terminated identically even if

only one side is being used. When fewer than all fifteen pairs are used,

identically terminate all the output pairs on the same package side

whether used or unused. If no outputs on a side are used, then leave all

these outputs open (unterminated). This will maintain minimum

output skew. Failure to do this will result in a 10–20ps loss of skew

margin (propagation delay) in the output(s) in use.

*For additional information, see Application Note

AND8002/D

The MC100LVE222, as with most ECL devices, can be operated

from a positive V supply in PECL mode. This allows the LVE222 to

be used for high performance clock distribution in +3.3V systems.

Designers can take advantage of the LVE222’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. All power supply

pins must be connected. For more information on using PECL,

designers should refer to Application Note AN1406/D. For a SPICE

model, see Application Note AN1560/D.
