Divider w/CML Output and
Internal Termination
Descriptions
The NB7L32M is an integrated
÷
2 divider with differential clock
inputs and asynchronous reset.
Differential clock inputs incorporate internal 50
resistors and accept LVPECL (Positive ECL), CML, or LVDS. The
high frequency reset pin is asserted on the rising edge. Upon
power
up, the internal flip
flops 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 termination which guarantees 400 mV output swing when
externally receiver terminated 50 to V
CC
(See Figure 16).
The device is housed in a small 3x3 mm 16 pin QFN package.
