The M2006-02 is a PLL (Phase Locked Loop) based
clock generator that generates output clocks synchro-
nized to one of two selectable input reference clocks.

reference divider values Mfec and Rfec.

• The inverse FEC PLL ratios (at top of Table 4) enable
the M2006-02-622.0800 to accept “base” input reference
frequencies of: 663.7255, 666.5143, 669.3266,
672.1627, and 622.08MHz.
Non-FEC ratio 3
Table 4: FEC PLL Ratio Dividers Look-up Table (LUT)
Note 1: The phase detector frequency (Fpd, which is calculated as
Fref/Rfec) should be above 1.5 MHz to prevent spurs on the
output clock. To ensure the PLL remains locked when using a
recovered clock (such as in loop timing mode), the phase
detector frequency should ideally be about 20MHz, or at least
less than 50 MHz.
Note 2: These table selections use the same or similar Mfec divider
values as the complementary selections noted. This allows the
use of the same loop filter component values and resulting PLL
loop bandwidth and damping factor values for complementary
selections. Complementary selections can be actively
switched in a given application.
• The Mfin feedback divider enables the actual input
reference clock to be the “base” input frequency
divided by 1, 4, 8, or 32. Therefore, for the base input
frequency of 622.08MHz, the actual input reference
clock frequencies can be: 622.08, 155.52, 77.76, and
19.44MHz. (See Table 3 on pg. 3.)
Note 3: In non-FEC applications, these settings can be used optimize
phase detector frequency or to actively change PLL loop
bandwidth.

VCSO BASED FEC CLOCK PLL
P r o d u c t D a t a S h e e t
The PLL
Relationship Among Frequencies and Dividers
The PLL uses a phase detector and configurable
dividers to synchronize the output of the VCSO with
selected reference clock.
The VCSO center frequency must be specified at time
of order. The relationship between the VCSO (Fvcso)
frequency, the Mfin divider, the Mfec divider, the Rfec
divider, and the input reference frequency (Fin) is:
The “Mfin Divider” and “Mfec Divider” divide the VCSO
frequency, feeding the result into the phase detector.
Mfec
Rfec
-------------
Fvcso = Fin × Mfin ×
The selected input reference clock is divided by the
“Rfec Divider”. The result is fed into the other input of
the phase detector.
As an example, for the M2006-02-622.0800, the non-FEC
and inverse-FEC PLL ratios in Table 4 enable use with
these corresponding input reference frequencies:
The phase detector compares its two inputs. It then
outputs pulses to the loop filter as needed to increase or
decrease the VCSO frequency and thereby match and
lock the divider output’s frequency and phase to those
of the input reference clock.

(+200ppm), appropriate selection of all of the following
are required for the PLL be able to lock: VCSO center
frequency, input frequency, and divider selections.
Table 6: Example FEC PLL Rations and Input Reference Frequencies
Note 1: Input reference clock (“Fin”) can be the base frequency
shown divided by “Mfin” (as shown in Table 3 on pg. 3).
Maintaining PLL Lock:
The narrow tuning range of the VCSO requires that the
input reference frequency must remain suitable for the
current look-up table selection. For example, when
switching between “Inverse FEC ratio” and “Non-FEC
ratio” look-up table selections (see Table 4 on pg. 3), the
input reference frequency must change accordingly in
order for the PLL to lock.
Outputs
The M2006-02 provides a total of two differential
LVPECL output pairs: FOUT1 and FOUT0. Because each
output pair has its own P divider, the FOUT1 pair and the
FOUT0 can output the two different frequencies at the
same time. For example, FOUT1 can output 155.52MHz
while FOUT0 outputs 622.08MHz.
An out-of-lock condition due to an inappropriate
configuration will typically result in the VCSO
operating at its lower or upper frequency rail,
which is approximately 200ppm above or below
the nominal VCSO center frequency.
Any unused output should be left unconnected
(floating) in the system application. This will
minimize output switching current and therefore
minimize noise modulation of the VCSO.

The various “Non-FEC ratio” settings can be used to
actively change PLL loop bandwidth in a given
application. See “FEC PLL Ratio Dividers Look-up
Table (LUT)” on pg. 3.
External Loop Filter
To provide stable PLL operation, and thereby a low jitter
output clock, the M2006-02 requires the use of an
external loop filter. This is provided via the provided
filter pins (see Figure 4).
Consult factory for external loop filter component
values.
Due to the differential signal path design, the
implementation requires two identical complementary
RC filters as shown here.
