NB6L72M
2.5V / 3.3V Differential 2 X 2
Crosspoint Switch with
CML Outputs
Multi−Level Inputs w/ Internal Termination
Description
The NB6L72M is a high−bandwidth fully differential 2 x 2
Crosspoint Switch with internal source termination and CML output
structure, optimized for low skew and minimal jitter.. The differential
inputs incorporate internal 50 W termination resistors and will accept
LVPECL, CML, LVDS, LVCMOS, or LVTTL logic levels. The
SELECT inputs are single−ended and can be driven with
LVCMOS/LVTTL.
The 16 mA differential CML outputs provide matching internal
50 W terminations and 400 mV output swings when externally
terminated with a 50 W resistor to VCC.
The device is offered in a small 3 mm x 3 mm 16−pin QFN package.
The NB6L72M is a member of the ECLinPS MAX™ family of
high performance products.
Features
• Maximum Input Clock Frequency > 3.0 GHz
• Maximum Input Data Rate > 5 Gb/s
• 360 ps Typical Propagation Delay
• 65 ps Typical Rise and Fall Times
• Differential CML Outputs, 400 mV peak−to−peak, typical
• Operating Range: VCC = 2.375 V to 3.63 V with GND = 0 V
• Internal Input and Output Termination Resistors, 50 W
• Functionally Compatible with Existing 2.5 V / 3.3 V LVEL, LVEP,
EP, and SG Devices
• −40°C to +85°C Ambient Operating Temperature
• These are Pb−Free Devices

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. 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.
4. CML outputs loaded with 50 W to VCC for proper operation.
5. Input and output parameters vary 1:1 with VCC.
6. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously.
7. Vth is applied to the complementary input when operating in single−ended mode.
8. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
9. VCMR minimum 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.
