NB6L572M 2.5V / 3.3V Differential 4:1 Mux to 1:2 CML Clock/Data Fanout / Translator Multi−Level Inputs w/ Internal Termination Description The NB6L572M is a high performance differential 4:1 Clock / Data input multiplexer and a 1:2 CML Clock / Data fanout buffer that operates up to 6 GHz / 8 Gbps respectively with a 2.5 V or 3.3 V power supply. The differential Clock / Data inputs have internal 50 W termination resistors and will accept differential LVPECL, CML, or LVDS logic levels. The NB6L572M incorporates a pair of Select pins that will choose one of four differential inputs and will produce two identical CML output copies of Clock or Data. As such, the NB6L572M is ideal for SONET, GigE, Fiber Channel, Backplane and other Clock/Data distribution applications. The two differential CML outputs will swing 400 mV when externally loaded and terminated with a 50 W resistor to VCC and are optimized for low skew and minimal jitter. The NB6L572M is offered in a low profile 5x5mm 32−pin QFN Pb−Free package. Application notes, models, and support documentation are available at www.onsemi.com. The NB6L572M is a member of the ECLinPS MAX™ family of high performance clock products. http://onsemi.com MARKING DIAGRAM 1 32 QFN32 MN SUFFIX CASE 488AM 1 NB6L 572M AWLYYWWG G A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information on page 8 of this data sheet.

Electrical parameters are guaranteed only over the declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied individually under normal operating conditions and not valid simultaneously. 5. Input and Output parameters vary 1:1 with VCC. 6. CML outputs loaded with 50 W to VCC for proper operation. 7. Vth is applied to the complementary input when operating in single−ended mode. 8. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously. 9. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously. 10. VCMR min varies 1:1 with GND, VCMR max varies 1:1 with VCC. The VCMR range is referenced to the most positive side of the differential input signal. http://onsemi.com 5 5 Page
