fanout buffer designed with clock distribution in mind. The
LVECL/LVPECL input signal pairs can be used in a differential
configuration or singleended (with V
BB
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. When the
output banks are configured with the
distributed. The LVEP222 specifically guarantees low output to output
skew. Optimal design, layout, and processing minimize skew within a
device and from lot to lot. This device is an improved version of the
MC100LVE222 with higher speed capability and reduced skew.
The fsel pins and CLK_Sel pin are asynchronous control inputs.
Any changes may cause indeterminate output states requiring an MR
pulse to resynchronize any 1/2X outputs (See Figure 3). Unused
output pairs should be left unterminated (open) to reduce power and
switching noise.
The NB100LVEP222, as with most ECL devices, can be operated
from a positive V
CC
/V
CC0
supply in LVPECL mode. This allows the
LVEP222 to be used for high performance clock distribution in
+2.5/3.3 V systems. 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. For a SPICE model, refer to
Application Note AN1560/D.
The V
BB
pin, an internally generated voltage supply, is available to
this device only. For singleended LVPECL input conditions, the
unused differential input is connected to V
BB
as a switching reference
voltage. V
BB
may also rebias AC coupled inputs. When used, decouple
V
BB
and V
CC
/V
CC0
via a 0.01 F capacitor and limit current sourcing
or sinking to 0.5 mA. When not used, V

should be left open.
