LMX9402 Frequency Synthesizer Module
General Description
The Frequency Synthesizer Module is a Low Temperature Co-fired Ceramic (LTCC) RF module consisting of a high performance frequency synthesizer, loop filter, and voltage controlled oscillator (VCO). The frequency synthesizer is fabricated using National's ABiC BiCMOS process (fT = 14 GHz). The loop filter and VCO are fabricated on National's Low Temperature Co-fired Ceramics. The Frequency Synthesizer Module can be used for local oscillator applications. Using a digital phase locked loop technique, the on board frequency synthesizer can generate a very stable, low noise local oscillator. Serial data is transferred into the module using a three wire interface. The loop filter is designed for fast lock times and maximum attenuation of reference spurs. The module is available in a Ball Grid Array 560 mil X 560 mil X 220 mil package.

Multiplexed output of the RF programmable dividers, reference dividers, or RF Lock Detect. Normally used as RF Lock Detect. Ground. Power supply voltage input to PLL. Ground. VCO Frequency Output. Ground. Power supply voltage input to VCO Ground. Binary serial data input. Data entered MSB first. LSB is control bit. High impedance CMOS input. Ground. Reference Oscillator input. High impedance CMOS Clock input. Data is clocked in on the rising edge, into the various counters and registers. Load Enable input (with internal pull-up resistor). When LE Load Enable transitions HIGH, data stored in the shift registers is loaded into the appropriate latch (control bit dependent). Clock must be low when LE toggles high or low. Ground.
