Description
Vectron s FX060 frequency translator is a low noise,
narrow band PLL that generates 155.52 MHz and
19.44 MHz output clocks locked to an input 8 kHz or
1.544 MHz reference clock. The 19.44 MHz clock is
generated by a low noise VCXO. The 155.52 MHz
signal is a multiplied representation of the 19.44 MHz
output.
