Please make sure that GND is the first pad to be bonded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The coordinates may vary depending on sawing width and location. However, the distances between pads are accurate.

With a 30 ppm/pF crystal typical values are MAS9283AN – AR > 90 ppm/V, MAS9283AA – AE > 75 ppm/V, MAS9283AG – AL > 60 ppm/V, MAS9283AT – AX > 50 ppm/V. Note 3: If the PD pin is floating the output buffer is active. Oscillator is always running. IC OUTLINES Figure 2. IC outline of MAS9283.

Quartz Crystal The MAS9283 VCXO function consists of the external crystal and the integrated VCXO oscillator circuit. To assure the best system performance (frequency pull range) and reliability, a crystal device with the recommended parameters (shown below) must be used, and the layout guidelines in the following section must be followed. The frequency of the oscillation of a quartz crystal is determined by its “cut” and by the load capacitors connected to it. MAS9283 incorporates on-chip variable load capacitors that “pull” (change) the frequency of the crystal. The crystal specified for use with the MAS9283 is designed to have zero frequency error when the total of on-chip + stray capacitance is 10 pF. See Note 3 on page 2 for other capacitance options. The external crystal must be connected as close to the chip as possible and should be on the same side of the PCB as the MAS9283. There should be no vias between the crystal pins and the X1 and X2 device pins. There should be no signal traces underneath or close to the crystal. Recommended Crystal Parameters: Parameter Symbol Typ Unit Initial Accuracy at 25°C ±20 ppm Temperature Stability Crystal Load Capacitance CL ±30 10 ppm pF Crystal Shunt Capacitance (Typical) C0 2 pF C0/C1 Ratio (Typical) Note 1) ≤ 300 Note 1. If the crystal with a load other than 10 pF is used with MAS9283, the crystal has to have frequency offset in order to have the nominal frequency at VC = 1.65 V. Please see table below for offset frequencies vs. crystal load. (Values are for a typical crystal with S = 30 ppm/pF.)
