General Description
The SY100ELT21L is a single differential LVPECL-to-LVTTL translator that uses a single +3.3V power supply. Because LVPECL (low voltage positive ECL) levels are used, only +3.3V and ground are required. The small outline 8-lead SOIC package and low skew single gate design make the ELT21L ideal for applications that require the translation of a clock or data signal where minimal space, low power, and low cost are critical.
VBB allows a differential, single-ended, or AC-coupled interface to the device. If used, the VBB output should be bypassed to VCC with a 0.01 μF capacitor.
Under open input conditions, the /D will be biased at a VCC/2 voltage level and the D input will be pulled to ground. This condition will force the Q output low to provide added stability.
The ELT21L is patible with positive ECL 100K logic levels.
