HMC440QS16G / 440QS16GE v03.0808 2.8 GHz INTEGER-N SYNTHESIZER (N = 2 - 32) Typical Applications The HMC440QS16G(E) is ideal for: • 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 8 INTEGER-N SYNTHESIZER - SMT Functional Diagram General Description The HMC440QS16G(E) is an Integer-n synthesizer that incorporates a 10 to 1300 MHz digital PhaseFrequency Detector with 10 to 2800 MHz 5-Bit Frequency Counter (continuous division from 2 to 32) in miniature 16 lead QSOP plastic packages. It is intended for use in low phase noise offsetsynthesizer applications. The HMC440QS16G(E)’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(E) generates an output voltage that can be used to phase lock a VCO to a reference oscillator.

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 v03.0808 2.8 GHz INTEGER-N SYNTHESIZER (N = 2 - 32) 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.
