General Description
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. It is fabricated using National's
0.5u ABiCV silicon BiCMOS process. The LMX237x contains 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
frequencies below 1.2 GHz. A 16/17 or an 8/9 prescaler can be selected 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 voltage
controlled oscillators (VCOs). Serial data is transferred into the LMX237x via a
1.8 V three wire interface (Data, Enable, Clock) compatible with low voltage
baseband processors. Supply voltage can range from 2.7V to 5.5V. The
LMX237x family features very low current consumption typically: LMX2370 -
6.0 mA at 3V, LMX2371 - 5.0 mA at 3V, LMX2372 - 4.0 mA at 3V.
The LMX237x are available in a 24-pad chip scale (CSP) or a 20-pin TSSOP
surface mount plastic package.
