General Description
The HMC363 is a low noise Divide-by-8 Static Divider
with InGaP GaAs HBT technology that has a small
size of 1.45 x 0.69 mm. This device operates from
DC (with a square wave input) to 12 GHz input frequency
with a single +5V DC supply. The low additive SSB
phase noise of -153 dBc/Hz at 100 kHz offset helps the
user maintain good system noise performance.

PWR SEL
In the low power mode, the power select pin is left floating.
By grounding this pin, the output power is increased by
approximately 10 dB.
9
PWR DWN
The power down pin is grounded for normal operation.
Applying 5 volts to this pin will power down this device.
10
DISABLE
The disable pin is grounded for normal operation.
Applying 5 volts to this pin will disable the input buffer amplifier.
