SY100ELT21L中文资料Translators数据手册Microchip规格书

描述 Description

The SY100ELT21Lis a singledifferential LVPECLto- LVTTL translators usinga single +3.3V power supply. Because LVPECL (Low Voltage Positive ECL) levelsare used, only +3.3V and ground are required. The small outline 8-lead SOICpackage and low skew single gate design make the ELT21L ideal for applicationsthat require the translation of a clock or data signal where minimal space, lowpower, and low cost are critical. VBB allowsa 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 openinput conditions, the /D will be biased at a VCC/2 voltage level and the Dinput will be pulled to ground. This condition will force the Q output low toprovide added stability. The 100ELTis compatible with positive ECL 100K logic levels.
