That puts it in the band for Ku-band satellite downconverters, point-to-point microwave backhaul, and high-frequency test equipment local oscillators — well beyond the reach of a standard 38 MHz PLL like the CD74HCT7046AE. The delta-sigma architecture allows fractional-N synthesis, so you can hit fine frequency steps without swapping the reference crystal. The part accepts a CMOS input and delivers a CMOS output, with a 3:2 input-to-output ratio and an on-chip divider and multiplier. ## Supply and temperature range for field deployment Supply voltage spans 2.5V to 3.6V, so a 3.3V rail is right in the sweet spot — no extra regulator needed if your board already runs 3.3V logic. The 0.50 mm pitch is manageable on a 4-layer board; a 2-layer board may struggle with fan-out on the inner pads. ## Active production — no last-time-buy pressure The part is supplied on tape and reel (TR) or cut tape (CT), so it fits both automated pick-and-place lines and prototype bench builds.","metaTitle":"LMX2487SQ/NOPB PLLatinum™ PLL Frequency Synthesizer – 6 GHz","metaDescription":"Texas Instruments LMX2487SQ/NOPB PLL frequency synthesizer, delta-sigma, 6 GHz max, 2.5V–3.6V supply, -40°C to 85°C, 24-WQFN.
