Part Number : LMX2531
Function : High Performance Frequency Synthesizer System with Integrated VCO
Package : 36 pin 6x6x0.8 mm WQFN Type
Maker : Texas Instruments
Pinouts : 
Description :
The LMX2531 is a low power, high performance frequency synthesizer system which includes a fully integrated delta-sigma PLL and VCO with fully integrated tank circuit. The third and fourth poles are also integrated and also adjustable. Also included are integrated ultra-low noise and high precision LDOs for the PLL and VCO which give higher supply noise immunity and also more consistent performance.
When combined with a high quality reference oscillator, the LMX2531 generates very stable, low noise local oscillator signals for up and down conversion in wireless communication devices. The LMX2531 is a monolithic integrated circuit, fabricated in an advanced BiCMOS process. There are several different versions of this product in order to accommodate different frequency bands. Device programming is facilitated using a three-wire MICROWIRE Interface that can operate down to 1.8 volts. Supply voltage range is 2.8 to 3.2 Volts. The LMX2531 is available in a 36 pin 6x6x0.8 mm WQFN Package.
