CDCD5704
SCAS823–DECEMBER 2006
The bypass mode routes the input clock REFCLK to the differential output buffers, bypassing the PLL.
To ensure that the CDCD5704 clock generator always performs correctly, the device switches off the PLL and
the outputs are in the high-impedance state, once the clock input is below 10 MHz. If the supply voltage VDD is
less than V
PUC
, all logic gates are reset, the PLL is powered down, and the outputs are in the high-impedance
state. Therefore, the device only starts its operation if these minimum requirements are met.
Because the CDCD5704 is based on PLL circuitry, it requires a stabilization time to achieve phase-lock of the
PLL. With use of an external reference clock, this signal must be fixed-frequency and fixed-phase prior to the
start of stabilization time.
The device operates from a single 2.5-V supply voltage. The CDCD5704 device is characterized for operation
from 0
°
C to 70
°
C.
