16. Clock generation
16.1 Crystal oscillator
The clock applied to the CLRC663 acts as time basis for generation of the carrier sent out
at TX and for the quadrature mixer I and Q clock generation as well as for the coder and
decoder of the synchronous system. Therefore stability of the clock frequency is an
important factor for proper performance. To obtain highest performance, clock jitter has to
be as small as possible. This is best achieved by using the internal oscillator buffer with
the recommended circuitry.
16.2 IntegerN PLL clock line
The CLRC663 is able to provide a clock with configurable frequency at CLKOUT from
1 MHz to 24 MHz (PLL_Ctrl_Reg and PLL_DIV_Reg). There it can serve as a clock
source to a microcontroller which avoids the need of a second crystal oscillator in the
reader system. Clock source for the IntegerN-PLL is the 27.12 MHz crystal oscillator.
Inside the PLL the input frequency is divided by 2: fin = 13.56 MHz.
Two dividers are determining the output frequency. First a feedback integer-N divider
configures the VCO frequency to be N
fin/2 (control signal pll_set_divfb). As supported
Feedback Divider Ratios are 23, 27 and 28 VCO frequencies can be
23
fin / 2 (312 MHz), 27 fin / 2 (366 MHz) and 28 fin / 2 (380 MHz). 23 is the
recommended value.
