NB6L11M 2.5V / 3.3V 1:2 Differential CML Fanout Buffer
Multi-Level Inputs w/ Internal Termination
Description http://onsemi.com MARKING DIAGRAM*
16 1 QFN-16 MN SUFFIX CASE 485G NB6L 11M ALYWG G

The NB6L11M is a differential 1:2 CML fanout buffer. The differential inputs incorporate internal 50 W termination resistors that are accessed through the VT pins and will accept LVPECL, LVCMOS, LVTTL, CML, or LVDS logic levels. The VREFAC pin is an internally generated voltage supply available to this device only. VREFAC is used as a reference voltage for single-ended PECL or NECL inputs. For all single-ended input conditions, the unused complementary differential input is connected to VREFAC as a switching reference voltage. VREFAC may also rebias capacitor-coupled inputs. When used, decouple VREFAC with a 0.01 mF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VREFAC output should be left open. The device is housed in a small 3x3 mm 16 pin QFN package. The NB6L11M is a member of the ECLinPS MAXt family of high performance clock products.
