Description for the LMX2594

The LMX2594 is a high-performance, wideband synthesizer that can generate any frequency from 10 MHz to 15 GHz without using an internal doubler, thus eliminating the need for sub-harmonic filters. The high-performance PLL with figure of merit of –236 dBc/Hz and high-phase detector frequency can attain very low in-band noise and integrated jitter. The high-speed N-divider has no pre-divider, thus significantly reducing the amplitude and number of spurs. There is also a programmable input multiplier to mitigate integer boundary spurs.

The LMX2594 allows users to synchronize the output of multiple devices and also enables applications that need deterministic delay between input and output. A frequency ramp generator can synthesize up to two segments of ramp in an automatic ramp generation option or a manual option for maximum flexibility. The fast calibration algorithm allows changing frequencies faster than 20 µs. The LMX2594 adds support for generating or repeating SYSREF (compliant to JESD204B standard) designed for low-noise clock sources in high-speed data converters. A fine delay adjustment (9-ps resolution) is provided in this configuration to account for delay differences of board traces.

The output drivers within LMX2594 deliver output power as high as 7 dBm at 15-GHz carrier frequency. The device runs from a single 3.3-V supply and has integrated LDOs that eliminate the need for on-board low noise LDOs.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
