NB7L86M D

NB7L86M
2.5V/3.3V 12 Gb/s Differential
Clock/Data SmartGate with
CML Output and Internal
Termination
The NB7L86M is a multi−function differential Logic Gate, which
can be configured as an AND/NAND, OR/NOR, XOR/XNOR, or 2:1
MUX. This device is part of the GigaComm family of high
performance Silicon Germanium products. The NB7L86M is an
ultra−low jitter multi−logic gate with a maximum data rate of 12 Gb/s
and input clock frequency of 8 GHz suitable for Data Communication
Systems, Telecom Systems, Fiber Channel, and GigE applications.
Differential inputs incorporate internal 50 W termination resistors
and accept LVNECL (Negative ECL), LVPECL (Positive ECL),
LVCMOS, LVTTL, CML, or LVDS. The differential 16 mA CML
output provides matching internal 50 W termination, and 400 mV
output swing when externally terminated 50 W to VCC.
The device is housed in a low profile 3x3 mm 16−pin QFN package.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit board

Functional operation of the device exceeding these conditions is not implied. Device specification limit values are applied individually

13. Measured by forcing VINPP (TYP) from a 50% duty cycle clock source. All loading with an external RL = 50 W to VCC.
Input edge rates 40 ps (20% − 80%).
14. Duty cycle skew is measured between differential outputs using the deviations of the sum of Tpw− and Tpw+ @1 GHz.
15. Device to device skew is measured between outputs under identical transition @ 1 GHz.
16. Additive RMS jitter with 50% duty cycle clock signal.
17. Additive peak−to−peak data dependent jitter with input NRZ data (PRBS 2^23−1).
18. VINPP (MAX) cannot exceed VCC − VEE. Input voltage swing is a single−ended measurement operating in differential mode.
