The NB6L11M is a differential 1:2 CML fanout buffer. The differential inputs incorporate internal 50 Ω termination resistors accessed through the VT pin and accept LVPECL, LVCMOS, LVTTL, CML, or LVDS logic levels. The VREFAC pin, the internally generated supply voltage, is provided only for this device. VREFAC is used as the reference voltage for single-ended PECL or NECL inputs. For the single-ended input case, the unused complementary differential input is connected to VREFAC as the switching reference voltage. The VREFAC also couples the capacitor to the input rebias. When used, decouple VREFAC with a 0.01 µF capacitor and limit source/sink current to 0.5 mA. When not in use, the VREFAC output should be left open. The device features a small 3x3 mm 16-pin QFN encapsulation. NB6L11M is a high-performance clock product of ECLinPS MAX series.
