_______________Detailed Description
MAX2310
The MAX2310 is intended for dual-band (PCS and cel-
lular) and dual-mode code division multiple access
(CDMA) and FM applications (Figure 1). The device
includes an IF variable-gain amplifier, quadrature
demodulator, dual VCOs, and dual-frequency synthe-
sizers (Figure 7). Dual VCOs are provided for applica-
tions using different IF frequencies for each mode or
band of operation. The analog FM output signal can be
configured for conversion to the I channel, or it may be
converted in quadrature to both the I and Q channels.
The MAX2310’s operation modes are described in
Table 1. These modes are set by programming the con-
trol register and setting logic levels on control pins. If
MODE is left floating, the internal register controls the
operation. If driven high or low, mode will override cer-
tain register bits, as shown in Table 1.
