SY89536LHZ-TR is a low phase noise, low jitter, three-output clock generator. This device adds a third output to industry standard high frequency clock generators, enabling new applications and reducing overall system cost. It is available in Pb-free and RoHS compliant package selections.

The SY89536LHZ-TR clock generator is targeted at applications such as wireless baseband, routers, switches, file storage and high-speed networking applications. It is intended to be used in applications that require three clock synchronous, such as Digital Radio Frequency Memories (DRFMs).

The SY89536LHZ-TR works on the principle of a phase-locked loop (PLL). The PLL is a closed-loop frequency control system which compares the phase spectrum of a reference signal with the output signal of a voltage-controlled oscillator (VCO). However, instead of using the output signal of the PLL to control the frequency, the SY89536LHZ-TR uses the reference signal to control the frequency and phase of the three clock outputs.

The SY89536LHZ-TR has three inputs, two of which are differential mode. The differential mode connections provide a high common-mode rejection, thus improving signal integrity. The third input is an on-chip reference signal.

The SY89536LHZ-TR has three outputs, each of which can be programmed for a frequency of about 150 MHz to about 4 GHz. The three outputs can be programmed independently, allowing for the selection of any combination of frequencies from the proposed range. The device also supports adjustable jitter levels, which can be programmed to 0.15ps RMS or less.

The SY89536LHZ-TR also has an integrated phase detector which uses the reference signal to continuously adjust the PLL frequency and phase to obtain the highest degree of accuracy. The device further uses a power-saving digital phase−frequency detector (PFD) that reduces the device\'s total power consumption and improves its overall performance.

Overall, the SY89536LHZ-TR is an ideal choice for high-speed clock generator applications, such as wireless baseband, routers, switches, and file storage. It provides high-performance, low-phase noise, low-jitter output frequencies from 150 MHz to 4 GHz with an adjustable jitter level of up to 0.15ps RMS or less. The programmable frequency range and adjustable jitter levels provide system design flexibility and make the SY89536LHZ-TR the ideal solution for modern clock generator applications.
