1.8 V/2.5 V Differential 2 x 2 Crosspoint Switch with CML Outputs Clock/Data Buffer/Translator Multi−Level Inputs w/ Internal Termination NB7V72M www.onsemi.com MARKING DIAGRAM* Description The NB7V72M is a high bandwidth, low voltage, fully differential 2 x 2 crosspoint switch with CML outputs. The NB7V72M design is optimized for low skew and minimal jitter as it produces two identical copies of Clock or Data operating up to 5 GHz or 6.5 Gb/s, respectively. As such, the NB7V72M 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 10). 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 11). The NB7V72M is the 1.8 V/2.5 V CML version of the NB7L72M 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 NB7V72M is a member of the GigaComm™ family of high performance clock products. 1 1 QFN−16 MN SUFFIX CASE 485G Maximum Input Data Rate > 6.5 Gb/s Data Dependent Jitter < 15 ps pk−pk Maximum Input Clock Frequency > 5 GHz Random Clock Jitter < 0.8 ps RMS, Max 150 ps Typical Propagation Delay 30ps Typical Rise and Fall Times Differential CML Outputs, 400 mV peak−to−peak, typical Operating Range: VCC = 1.71 V to 2.625 V with GND = 0 V Internal 50 W Input Termination Resistors QFN−16 Package, 3mm x 3mm −40°C to +85°C Ambient Operating Temperature These are Pb−Free Devices NB7V 72M ALYWG G A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) *For additional marking information, refer to Application Note AND8002/D.
