Pllatinum?⠄ual Frequency Synthesizer For Rf Personal Communications - National Semiconductor

The LMX2370 LMX2371 LMX2372 family of monolithic, integrated dual fre- quency synthesizers, including prescalers, is designed to be used as a first and second local Oscillator for dual mode or dual conversion transceivers. It is fabricated using Nationals 0.5u ABiCV silicon BiCMOS process. The LMX2370 LMX2371 LMX2372 con- tains two dual modulus prescalers. A 32/33 or a 16/17 prescaler CAN be selected for the 2.5 GHz and 2.0 GHz RF synthesizers with the 16/17 prescaler rated for input frequen- cies below 1.2 GHz. A 16/17 or an 8/9 prescaler CAN be se- lected for the 1.2 GHz RF synthesizers with the 8/9 prescaler rated for input frequencies below 550 MHz. Using a digital Phase locked loop technique, the LMX237X CAN generate very stable, low noise control signals for UHF and VHF volt- age controlled Oscillators (VCOs). Serial data is transferred into the LMX2370 LMX2371 LMX2372 via a 1.8V three wire Interface (Data, En- able, Clock) compatible with low voltage baseband proces- sors. Supply voltage CAN range from 2.7V to 5.5V. The LMX2370 LMX2371 LMX2372 family features very low current consumption typi- cally: LMX2370 - 6.0 mA @ 3V, LMX2371 - 5.0 mA @ 3V, LMX2372 - 4.0 mA @ 3V By National Semiconductor Corporation
