DESCRIPTION
●The SY100EPT21L is a single, differential LVPECL to-LVTTL translator using a single +3.3V power supply. Because low voltage positive ECL (LVPECL) levels are used, only +3.3V and ground are required. The small outline 8-pin SOIC package and low-skew, single-gate design make the EPT21L 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 0.01µF 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.
