Proprietary Information and Specifications are Subject to Change
Voltage Controlled Oscillators (VCOs)__________________
The active cores of the two VCOs are present on the CX74001,
requiring only differential external LC tanks and a PLL
synthesizer. The VCO core current is automatically adjusted to
give a constant VCO output swing, regardless of the external
tank Q.
Mode Control ______________________________________
The operation of the chip is controlled by signals CELL/PCS,
FM, and SLEEP. The Single IF (SIF) is added to use a common
IF frequency for CDMA mode in cellular and PCS band. This
allows the use of one IF SAW filter for the PCS and CDMA
modes to reduce system implementation cost. The logic blocks
are powered off of the Vcc_IF, so it must be present to obtain
chip functionality.
Electrical and Mechanical Specifications.
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
CX74001 are provided in Table 2. The recommended operating
conditions are specified in Table 3. Electrical specifications are
provided in Table 4. Tables 5, 6, 7, and 8 provide logic and
mode control information for the CX74001.
Figures 3 through 46 provide typical performance
characteristics. A schematic diagram of the CX74001 is
provided in Figure 47 and the package dimensions of the 48-pin
RFLGA are shown in Figure 48.
ESD Sensitivity
The CX74001 is a JEDEC Class 1 device. The following
extreme Electrostatic Discharge (ESD) precautions are required
according to the Human Body Model (HBM):
Protective outer garments.
Handle device in ESD safeguarded work area.
Transport device in ESD shielded containers.
Monitor and test all ESD protection equipment.
The HBM ESD withstand threshold value, with respect to
ground, is
±
1.5 kV. The HBM ESD withstand threshold value,
with respect to VDD (the positive power supply terminal) is also
±
1.5 kV.
