CS44600
Figure 28 shows the recommended crystal circuit layout. U1 is the CS44600. C1 and C2 are the VDX power supply
decoupling capacitors. Y1 is the crystal and C3, C4, L1 and C5 are the associated components for the crystal circuit.
L1 and C5 are only used for 3rd overtone crystals. C3 and C4 should have a C0G (NPO) dielectric. Care should be
taken to minimize the distance between the CS44600 XTI/XTO pins and C3. Top and bottom ground fill should be
used as much as possible around and in between all crystal circuit components to minimize noise.
