NB7N017M
3.3V SiGe 8Bit Dual
Modulus Programmable
Divider/Prescaler with CML
Outputs
The NB7N017M is a high speed 8–bit dual modulus
programmable divider/prescaler with 16 mA CML outputs capable
of switching at input frequencies greater than 3.5 GHz. The CML
output structure contains internal 50 source termination resistor to
V
CC
. The device generates 400 mV output amplitude with 50
receiver resistor to V
CC
. This I/O structure enables easy
implementation of the NB7N017M in 50 systems.
The differential inputs contain 50 termination resistors to VT
pads and all differential inputs accept RSECL, ECL, LVDS,
LVCMOS, LVTTL, and CML.
Internally, the NB7N017M uses a > 3.5 GHz 8–bit programmable
down counter. A select pin, SEL, is used to select between two
words, Pa[0:7] and Pb[0:7], that are stored in REGa and REGb
respectively. Two parallel load pins, PLa and PLb, are used to load
the level triggered programming registers, REGa and REGb,
respectively. A differential clock enable, CE, pin is available.
The NB7N017M offers a differential output, TC. Terminal count
output, TC, goes high for one clock cycle when the counter has
reached the all zeros state. To reduce output phase noise, TC is
retimed with the rising edge triggered latches.
