| HMC440QS16G / 440QS16GE v02.0705 HBT DIGITAL PHASE-FREQ. DETECTOR, 10 - 1300, MHz w/ 5-BIT COUNTER, 10 - 2800 MHz 5 FREQUENCY DIVIDERS & DETECTORS - SMT Typical Applications This Phase Frequency Detector w/ integrated Counter is a key component in low phase noise frequency synthesis applications such as: * Satellite Communication Systems * Point-to-Point Radios * Military Applications * Sonet Clock Generation Features Ultra Low SSB Phase Noise Floor: -153 dBc/Hz@10 kHz offset @ 100 MHz Reference Frequency. Programmable Divider (N= 2-32) Operating up to 2.8 GHz Open Collector Output Buffer Amplifiers for Interfacing w/ Op-Amp Based Loop Filter QSOP16G SMT Package: 29.4 mm2 Functional Diagram General Description The HMC440QS16G & HMC440QS16GE integrate 10 to 1300 MHz digital Phase-Frequency Detectors with 10 to 2800 MHz 5-Bit Counters (continuous division from 2 to 32) in miniature 16 lead QSOP plastic packages. It is intended for use in low phase noise offset-synthesizer applications. The HMC440QS16G & HMC440QS16GE's combination of high frequency operation along with ultra low phase noise floor make possible synthesizers with wide loop bandwidth and low N resulting in fast settling and very low phase noise. When used in conjunction with a differential loop amplifier, the HMC440QS16G & HMC440QS16GE generate an output voltage that can be used to phase lock a VCO to a reference oscillator.

DETECTOR, 10 - 1300, MHz w/ 5-BIT COUNTER, 10 - 2800 MHz v02.0705 Applications Information Simplified Block Diagram of 5-Bit Counter 5 FREQUENCY DIVIDERS & DETECTORS - SMT 5 - 109 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) 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: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC440QS16G / 440QS16GE v02.0705 HBT DIGITAL PHASE-FREQ. DETECTOR, 10 - 1300, MHz w/ 5-BIT COUNTER, 10 - 2800 MHz 5 FREQUENCY DIVIDERS & DETECTORS - SMT 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) Parameter 0.5 GHz 200 ps 700 ps 1 GHz 200 ps 300 ps 2 GHz 200 ps 120 ps tSETUP tHOLD Programmable Divider Timing Requirements for Synchronous Programming t OUT SU t HOLD OUT Rising Edge to Clock New Data A0-A4 CURRENT DATA NEW DATA IN Data Load Rising Edge 5 - 110 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC440QS16G / 440QS16GE v02.0705 HBT DIGITAL PHASE-FREQ.
