Frequently Asked Questions
What is the maximum output frequency supported by the LMX2487ESQENOPB?
The LMX2487ESQENOPB supports output frequencies up to 4 GHz, making it suitable for wideband RF applications including base stations, point-to-point radios, and test equipment requiring high-frequency synthesis across a broad range.
How does the delta-sigma modulator order affect spur performance in LMX2487ESQENOPB?
The LMX2487ESQENOPB features a programmable 12-bit delta-sigma modulator with selectable order from 1st to 4th. Higher modulator orders push fractional spurs further from the carrier, typically beyond 100 kHz offset, improving spectral purity at the cost of slightly increased in-band noise.
Which package does the LMX2487ESQENOPB use and what are its thermal advantages?
The LMX2487ESQENOPB is housed in a 36-pin Quad Flat No-Lead (QFN) package measuring approximately 6 mm x 6 mm, providing excellent thermal dissipation through its exposed pad, a compact PCB footprint, and low parasitic inductance for improved RF performance.
Can LMX2487ESQENOPB replace LMX2485 in existing designs?
Yes, the LMX2487ESQENOPB is a pin-compatible upgrade to the LMX2485, adding 4th-order delta-sigma modulation and extending the frequency range to 4 GHz versus 2.6 GHz, while retaining the same 3.3 V supply and SPI programming interface for a drop-in replacement.
