input on CDB5376 can receive a lower-frequency system clock and create a synchronous higher-frequen-
cy clock using an on-board PLL.
The expected input clock frequency to the BNC clock input is set by the EXT_CLK jumper (J16). If no ex-
ternal clock is supplied to CDB5376, the PLL will free-run at the nominal output frequency.
The PLL on CDB5376 uses a voltage-controlled crystal oscillator (VCXO) to minimize jitter, and has a sin-
gle-gate phase/frequency detector and clock divider to minimize size and power.
