General Description
The LMX237X 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 National鈥檚
0.5u ABiCV silicon BiCMOS process. The LMX237X 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 (VCO鈥檚). Serial data is transferred
into the LMX237X 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
LMX237X family features very low current consumption typi-
cally: LMX2370 - 6.0 mA
