The LMX237X family of monolithic, integrated dual frequency synthesizers, including prescalers, is designed to be used as a first and second local oscillator for dual mode or dual conversion transceivers.
The LMX237X family includes monolithic integrated dual frequency synthesizers with prescalers designed for use as first and second local oscillators in dual mode or dual conversion transceivers. The devices are fabricated using National's 0.5u ABiCV silicon BiCMOS process and support frequencies up to 2.5 GHz.
| Power Supply Voltage Range | 2.7V to 5.5V |
|---|---|
| Typical Current Consumption (LMX2370) | 6.0 mA @ 3V |
| Main PLL Operating Frequency Range | 45 MHz to 1200 MHz (P=16/17) |
| Auxiliary PLL Operating Frequency Range | 45 MHz to 1200 MHz (P=16/17) |
The typical current consumption is 6.0 mA @ 3V for LMX2370, 5.0 mA @ 3V for LMX2371, and 4.0 mA @ 3V for LMX2372.
The supply voltage can range from 2.7V to 5.5V.
The LMX2370 supports a 32/33 or a 16/17 prescaler selection.
