Figure 15. Modulation Data Register (Write Only)
The Modulation Data Register is used to load the modulation data
samples to the modulation unit. This value is transferred to the
modulation unit on the falling edge of Fpd_main where it is passed to
the main
Σ modulator at the selected magnitude offset on the
next falling edge of Fpd_main. Modulation Data Register values are
2's complement format. As shown in Figure 15, the value to be
loaded is:
Modulation Data Bits = Modulation data samples that represent
the desired instantaneous frequency offset to the selected main
synthesizer frequency (selected channel) before being affected
by the modulation data magnitude offset.
Electrical and Mechanical Specifications
The CX72302 is supplied as a 28-pin EP-TSSOP. The exposed pad
is located on the bottom side of the package and must be
connected to ground for proper operation. The exposed pad
should be soldered directly to the circuit board.
Signal pin assignments and functional pin descriptions are
specified in Table 5. The absolute maximum ratings of the
CX72302 are provided in Table 6. The recommended operating
conditions are specified in Table 7 and electrical specifications
are provided in Table 8.
Figure 16 provides a schematic diagram for the CX72302.
Figure 17 shows the package dimensions for the 28-pin
EP-TSSOP and Figure 18 provides the tape and reel dimensions.
Electrostatic Discharge (ESD) Sensitivity
The CX72302 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.
