APPLICATION INFORMATION
This section includes information on the optional
external crystal and on the external loop filter.
External Crystal Specifications
If an external crystal is used with the on-chip crystal
oscillator circuit (XTAL OSC), the external crystal
should have the following general specifications:
The external crystal will be applied to the XTAL_1 / REF_IN
and XTAL_2 input pins. External crystal load capacitors
are also required.
Recommended External Crystal Configuration
XTAL Load Capacitance Specification = 18 pF
C1
= 27 pF
C2
= 33 pF
External load capacitors C1 and C2 present a load of 15 pf
to the crystal (they are seen in series by the crystal through
the common ground connection). With the additional of PCB
trace capacitance and M906-02 input capacitance, the total
load to the crystal is about 18 pf.
External Loop Filter
To provide stable PLL operation, and thereby a low jitter
output clock, the M906-02 requires the use of an
external loop filter. This is provided via the provided
filter pins (see Figure 5).
Figure 5: External Loop Filter
The loop filter is implemented as a differential circuit
to minimize system noise interference. Due to the
differential signal path design, the implementation
requires two identical complementary RC filters as
shown here. See Table 4, Example External Loop Filter
Component Values, below.
