NB7L32M/D
NB7L32M
2.5V/3.3V, 14GHz ÷2 Clock
Divider w/CML Output and
Internal Termination
Description
The NB7L32M is an integrated
÷2 divider with differential clock
inputs and asynchronous reset.
Differential clock inputs incorporate internal 50
W termination
resistors and accept LVPECL (Positive ECL), CML, or LVDS. The
high frequency reset pin is asserted on the rising edge. Upon
powerup, the internal flipflops will attain a random state; the reset
allows for the synchronization of multiple NB7L32M’s in a system.
The differential 16 mA CML output provides matching internal
50
W termination which guarantees 400 mV output swing when
externally receiver terminated 50
The device is housed in a small 3x3 mm 16 pin QFN package.
