Figure 1. MAX2310 Typical Operating Circuit

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.

_______________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
