DESCRIPTION
The SY10/100ELT21 are single differential PECL-toTTL translators. Because PECL (Positive ECL) levels are
used, only +5V and ground are required. The small outline
8-lead SOIC package and low skew single gate design
make the ELT21 ideal for applications that require the
translation of a clock or data signal where minimal space,
low power, and low cost are critical.
The VBB output allow differential single-ended, or ACcoupled interface to the device. If used, the VBB output
should be bypassed to VCC with a 0.01µF capacitor.
The ELT21 is available in both ECL standards: the
10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
logic levels.

2. These parameters are guaranteed, but not tested.
3. Frequency at which output levels will meet a 0.8V to 2.0V minimum swing.
4. The fMAX value is specified as the minimum guaranteed maximum frequency. Actual operational maximum frequency may be greater.
5. 200mV input guarantees full logic at output.
