Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or
left floating. 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.

Note 1: An RS < 15 Ω crystal provides 56 MHz maximum frequency (i.e. negative resistance typically 30 Ω). With
an RS = 70 Ω crystal the maximum frequency is typically 40 MHz (i.e. negative resistance typically 110 Ω).
Note 2: VC sensitivity value depends on the crystal used. 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.

EXTERNAL COMPONENT SELECTION
MAS9283 requires a minimum number of external components for proper operation.
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.

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.)
