Test Conditions/Comments
Application example based on a typical setup using an
external 245.76 MHz VCXO (Toyocom TCO-2112);
reference = 15.36 MHz; R = 1
Integration BW = 200 kHz to 5 MHz
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
Integration BW = 200 kHz to 5 MHz
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
Integration BW = 200 kHz to 5 MHz
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
Test Conditions/Comments
Distribution section only; does not include
PLL and VCO; measured at rising edge of
clock signal
BW = 12 kHz − 20 MHz
BW = 12 kHz − 20 MHz
