3、 Product description
In the case of 15MHz to 15MHz, there is no need to use an internal harmonic synthesizer in the frequency range of 25ghz. High performance PLL with quality factor of - 236dbc / Hz and high phase detector frequency can achieve very low in band noise and integrated jitter. High speed n divider without pre
Frequency divider, thus significantly reducing the amplitude and number of spurious. There is also a programmable input multiplier to reduce integer boundary spurious.
Lmx2594 allows users to synchronize the outputs of multiple devices and can be applied when a delay is determined between input and output. The frequency ramp generator can synthesize up to 2 ramps in the automatic ramp generation option or manual option for maximum flexibility. The frequency can be accelerated to more than 20 μ s by fast calibration algorithm. Lmx2594 added pair generation or double
With the support of sysref (conforming to jesd204b standard), it becomes an ideal low noise clock source for high-speed data converter. Fine delay adjustment (9ps resolution) is provided in this configuration to solve the delay difference of board trace.
The output driver of lmx2594 can provide a certain output power when the carrier frequency is 15GHz. The device uses a single 3.3V power supply, and has an integrated Ti industry very low noise LDO, without on-board low noise LDO.
