LMX2430/LMX2433/LMX2434 PLLatinum™ Dual High Frequency Synthesizer for RF Personal Communications
The LMX243x devices are high performance frequency synthesizers with integrated dual modulus prescalers, designed for use as RF and IF local oscillators for dual conversion radio transceivers. The family includes the LMX2430 (3.0 GHz/0.8 GHz), LMX2433 (3.6 GHz/1.7 GHz), and LMX2434 (5.0 GHz/2.5 GHz). Using a proprietary digital phase locked loop technique, these devices generate very stable, low noise control signals for RF and IF voltage controlled oscillators.
| Supply Voltage | 2.25V to 2.75V |
|---|---|
| RF Operating Frequency (LMX2430) | 250 MHz to 3000 MHz |
| RF Operating Frequency (LMX2434) | 1000 MHz to 5000 MHz |
| Package Types | 20-Pin TSSOP and 20-Pin UTCSP |
The LMX2434 RF synthesizer allows selection of a 16/17 or a 32/33 prescale ratio.
The LMX2430 consumes 2.8 mA for the RF synthesizer and 1.4 mA for the IF synthesizer at 2.50V.
A low voltage logic interface allows direct connection to 1.8V devices.
