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 0.01F 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. |
