PLLatinum Dual Frequency Synthesizer System With Integrated VCOs

LMX2522 and LMX2532 are highly integrated, high performance, low power Frequency Synthesizer systems optimized for Korean PCS (K-PCS) with GPs and Korean Cellular (K-Cellular) with GPs CDMA (1xRTT, IS-95) mobile handsets. Using a proprietary digital Phase locked loop technique, LMX2522 and LMX2532 generate very stable, low noise local Oscillator signals for up and down conversion in Wireless Communications devices.
LMX2522 and LMX2532 include a RF voltage controlled Oscillator (VCO), a GPs VCO a loop Filter and a fractional-N RF PLL based on a delta sigma Modulator In concert these blocks form a closed loop RF and GPs synthesizer system. LMX2522 supports the Korean PCS band with GPs and LMX2532 supports the Korean Cellular band with GPs
LMX2522 and LMX2532 include an Integer-N IF PLL also. For more flexible loop Filter designs, the IF PLL includes a 4-level programmable Charge Pump Together with an external VCO and loop Filter LMX2522 and LMX2532 make a complete closed loop IF synthesizer system.
Serial data is transferred to the device via a three-wire MICROWIRE Interface (DATA, LE, CLK).
Operating supply voltage ranges from 2.7 V to 3.3 V. LMX2502 and LMX2512 feature low current consumption: 17 mA at 2.8 V.
LMX2522 and LMX2532 are available in a 28-pin leadless leadframe package (LLP).
