2.5V/3.3V1:20 Differential
HSTL/ECL/PECL Clock Driver
The NB100LVEP221 is a low skew 1-to-20 differential clock
driver, designed with clock distribution in mind, accepting two clock
sources into an input multiplexer. The two clock inputs are differential
ECL/PECL; CLK1/CLK1 can also receive HSTL signal levels. The
LVPECL input signals can be either differential configuration or
single-ended (if the V
BB
output is used).
The LVEP221 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 should be
terminated identically into 50 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 NB100LVEP221, as with most other ECL devices, can be
operated from a positive V
CC
supply in LVPECL mode. This allows the
LVEP221 to be used for high performance clock distribution in +3.3 V or
+2.5 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 PECL terminations, designers should
refer to Application Note AND8020/D.
The V
BB
pin, an internally generated voltage supply, is available to this
device only. For single-ended 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
via a 0.01 F capacitor and limit current sourcing or sinking to
0.5 mA. When not used, V
BB
should be left open.
Single-ended CLK input operation is limited to a V
