NB7N017M
3.3V SiGe 8-Bit Dual
Modulus Programmable
Divider/Prescaler with CML
Outputs
The NB7N017M is a high speed 8bit 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
W source termination resistor to
V
CC
. The device generates 400 mV output amplitude with 50
W
receiver resistor to V
CC
. This I/O structure enables easy
implementation of the NB7N017M in 50
W systems.
The differential inputs contain 50
W 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 8bit 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.

1. All high speed inputs and outputs are differential to improve performance.
2. All single-ended inputs are CMOS and NECL/ECL compatible.
3. All V
CC
and V
EE
pins must be externally connected to external power supply voltage to guarantee proper device operation. The thermally
exposed pad (EP) on package bottom (see case drawing) must be attached to a heat-sinking conduit. Exposed pad is bonded to the lowest
voltage potential, V
EE
.
4. The NC pins are electrically connected to the die and must be left open.
5. CML outputs require 50 W receiver termination resistor to V
CC
for proper operation.
6. In the differential configuration when the input termination pins are connected to the common termination voltage, and if no signal is applied
then the device will be susceptible to self-oscillation.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.

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.

Application Information
All NB7N017M inputs can accept PECL, CML, LVTTL,
LVCMOS and LVDS signal levels. The limitations for
differential input signal (LVDS, PECL, or CML) are
minimum input swing of 100 mV and the maximum input
swing of 450 mV. Within these conditions, the input
voltage can range from V
CC
to 1.2 V. Examples interfaces
are illustrated below in a 50
W environment (Z = 50 W).
