2.2 Main Analog Characteristics
The SMT321 comes in two different configurations. The main differences on the two
modules are clock generation and analog signal generation. Table 2 shows the
configuration of the lower frequencies module. Table 1 shows the frequencies attainable
by the various VCO’s implemented on the SMT321. The high frequency configuration
board is shown in Table 3.
VCO Model Number Minimum Frequency Maximum Frequency
UMS-150-A16 75MHz 150MHz
UMS-300-A16 150MHz 300MHz
UMS-535-A16 300MHz 535MHz
UMS-1000-A16 500MHz 1000MHz
