HMC394LP4 v04.1102 MICROWAVE CORPORATION GaAs HBT PROGRAMMABLE 5-BIT COUNTER, DC - 2.2 GHz FREQ. DIVIDER & DETECTORS - SMT 10 Typical Applications Features Programmable divider for offset synthesizer and variable divide by N applications: SSB Phase Noise: -153 dBc/Hz @ 100 kHz Selectable Division from 2 to 32 • Satellite Communication Systems Parallel 5-Bit Control • Pt-Pt and Pt-MPt Radios Wide Input Power Range: -20 to +10 dBm • LMDS 4mm x 4mm Leadless SMT Package • SONET General Description Functional Diagram The HMC394LP4 is a low noise GaAs HBT programmable 5-bit counter in a 4mm x 4mm leadless surface mount package. 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.

DIVIDER & DETECTORS - SMT 10 The circuit board used in the final 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. Note: C1 and C3 bypass capacitors are not necessary if power supply trace is short. Note: The evaluation PCB for the HMC394LP4 contains 10K Ohm pull up resistors for each of the five control inputs A0 through A4. Programming the 31 distinct division ratios consists of installing or removing jumpers S1 through S5, as shown below.

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) FREQ. DIVIDERS & DETECTORS - SMT 10 As an example, if the input frequency is 1 GHz, the maximum settling time is 32 nS For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com 10 - 63 MICROWAVE CORPORATION HMC394LP4 v04.1102 GaAs HBT PROGRAMMABLE 5-BIT COUNTER, DC - 2.2 GHz Synchronous Programming FREQ. DIVIDER & DETECTORS - SMT 10 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.
