| 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.

Positive Supply Voltage Negative Supply Voltage Negative Supply Voltage Positive Supply Voltage The Exposed Pad (EP) on the QFN-16 package bottom is thermally connected to the die for improved heat transfer out of package. The exposed pad must be attached to a heat-sinking conduit. The pad is not electrically connected to the die, but is recommended to be electrically and thermally connected to VEE on the PC board. 1. In the differential configuration when the input termination pins (VTD, VTD) are connected to a common termination voltage or left open, and if no signal is applied on D/D input, then, the device will be susceptible to self-oscillation. 2. All VCC and VEE pins must be externally connected to a power supply for proper operation. http://onsemi.com 2 NB6L11M Table 2.
