| NB7L72M 2.5V / 3.3V Differential 2 x 2 Crosspoint Switch with CML Outputs Clock/Data Buffer/Translator Multi-Level Inputs w/ Internal Termination Description http://onsemi.com MARKING DIAGRAM* 1 1 QFN-16 MN SUFFIX CASE 485G 16 NB7L 72M ALYWG G The NB7L72M is a high bandwidth, low voltage, fully differential 2 x 2 crosspoint switch with CML outputs. The NB7L72M design is optimized for low skew and minimal jitter as it produces two identical copies of Clock or Data operating up to 7 GHz or 10 Gb/s, respectively. As such, the NB7L72M is ideal for SONET, GigE, Fiber Channel, Backplane and other clock/data distribution applications. The differential IN/IN inputs incorporate internal 50 W termination resistors and will accept LVPECL, CML, or LVDS logic levels (see Figure 11). The 16 mA differential CML outputs provide matching internal 50 W terminations and produce 400 mV output swings when externally terminated with a 50 W resistor to VCC (see Figure 9). The NB7L72M is the 2.5 V/3.3 V version of the and NB7V72M and is offered in a low profile 3x3 mm 16-pin QFN package. Application notes, models, and support documentation are available at www.onsemi.com. The NB7L72M is a member of the GigaCommTM family of high performance clock products.

Internal 50 W Termination Pin for IN0 and IN0 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 electrically connected to the die, and is recommended to be electrically and thermally connected to GND on the PC board. Description 1. In the differential configuration when the input termination pins (VT0, VT1) are connected to a common termination voltage or left open, and if no signal is applied on INx/INx input, then the device will be susceptible to self-oscillation. 2. All VCC and GND pins must be externally connected to a power supply for proper operation. http://onsemi.com 2 NB7L72M Table 3.
