Functional Diagram
General Description
The HMC394LP4 & HMC394LP4E are low noise
GaAs HBT programmable 5-bit counters in 4 x
4mm leadless surface mount packages. This device
allows continuous division from N= 2 to 32 at input
frequencies up to 2.2 GHz. The output voltage swing is
800 mV with a duty cycle inversely proportional to N.
The low additive SSB phase noise of -153 dBc/Hz at
100 KHz offset makes this counter an excellent choice
for low noise synthesizer applications.

Evaluation PCB
The circuit board used in the application should use RF circuit design techniques. Signal lines should have 50
Ohm impedance while the package ground leads and backside ground slug should be connected directly to
the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and
bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.

5-BIT COUNTER, DC - 2.2 GHz
Applications Information
Simplified Block Diagram
Asynchronous Programming
The 5-Bit programmable counter counts-down from the programmed value of the data bits to zero and issues an
output pulse at the end of each cycle. Settling time of the programmable 5-Bit counter is defined as the maximum
time required for the counter to change the division ratio N to a new value after the data bits have settled. The worst
case settling time occurs if the data bits A0 thru A4 are changing during the load cycle. Under this condition, the
data bits may potentially be erroneous when they are clocked in and in the worst case could be all 1’s, requiring 32
clock cycles until the correct data is re-loaded into the flip flops. The worst case asynchronous settling time can be
calculated as follows:
TSETTLING MAX = 32/fIN (For Asynchronous Programming)
4
Frequency Dividers & Detectors - SMT
v09.0114
As an example, if the input frequency is 1 GHz, the maximum settling time is 32 nS

Synchronous Programming
For applications which can not tolerate a momentary undefined division ratio, which normally occurs while changing
the data bits (A0-A4) at random, synchronous programming can be used. Data is loaded into the counter on every
rising edge of the clock which occurs while the output (OUT) is “HIGH”. The typical minimum setup and hold times are
shown in the table below as a function of frequency. For precision applications, the rising edge of the complementary
output may be used to latch the new data bits (A0-A4), so that all bits are settled before the next load cycle.
TSETTLING MAX = N/fIN (For Synchronous Programming)
Where N is the desired division ratio, and fIN = Input Frequency (Hz)
