Functional Description
The MK2069-01 is a PLL (phase locked loop) based clock
generator that generates output clocks synchronized to an
input reference clock. It contains two cascaded PLL’s with
user selectable divider ratios.
The first PLL is VCXO-based and uses an external pullable
crystal as part of the normal “VCO” (voltage controlled
oscillator) function of the PLL. The use of a VCXO assures
a low phase noise clock source even when a low PLL loop
bandwidth is implemented. A low loop bandwidth is needed
when the input reference frequency is low, or when jitter
attenuation of the input reference is desired.
The second PLL is used to translate or multiply the
frequency of the VCXO PLL which has a maximum output
frequency of 27 MHz. This second PLL, or Translator PLL,
uses an on-chip VCO circuit that can provide an output clock
up to 160 MHz. The Translator PLL uses a high loop
bandwidth (typically greater than 1 MHz) to assure stability
of the VCO clock output. It requires a stable, high frequency
input reference which is provided by the VCXO PLL.
The divide values of the divider blocks within both PLLs are
set by device pin configuration. This enables the system
designer to define the following:
Input clock frequency
VCXO crystal frequency
VCLK output frequency
RCLK output frequency, which is also the phase detector
frequency of the VCXO PLL.
TCLK output frequency
Any unused clock or logic outputs can be tri-stated to reduce
interference (jitter, phase noise) on other clock outputs.
Outputs can also be tri-stated for system testing purposes.
External components are used to configure the VCXO PLL
loop response. This serves to maximize loop stability and to
achieve the desired input clock jitter attenuation
characteristics.
