Description



Application

• Supports IS-98 (CDMA) and IS-19 (AMPS) standards for dual-mode operation
• 2.7 to 3.15 V supply voltage
• Low current: 26 / 21 mA in CDMA Rx / FM Rx Modes
• Rx power control through 90 dB dynamic range AGC amplifier
• IF mixer for downconverting IF to analog baseband
• Low-pass filtering for CDMA and FM I- and Q-component baseband signal demodulation
• 4-bit ADCs convert CDMA I and Q analog baseband components to digital baseband
• 8-bit ADCs convert FM I and Q analog baseband to digital baseband
• Clock generators for CDMA / AMPS operation
• VCO for generation of Rx LO mixing signal
• I- and Q-channel DC offset control inputs drive baseband DC voltage offset to zero in CDMA and FM signal paths
• Operational Mode compatibility with the MSM2300™, MSM3000® and MSM3100™ devices
• Enhanced features with MSM3000 device through three-line serial bus interface (SBI):
Slotted FM Mode
Selective power-down
Mode selection
• 48-lead LQFP and 48-pin BCC packaging options for dense circuit assemblies

Description

The QUALCOMM IFR3000™ and IFT3000™ Rx and Tx IF/Baseband processors offer significant reduction in cost, size and pin count over previous generation products. By integrating the functionality of three Application Specific Integrated Circuits (ASICs) into two ASICs, designers now possess IF-to-Baseband and Baseband-to-IF processing power, and Rx and Tx Automatic Gain Control (AGC) circuitry on either two 48-pin Low-profile Quad Flat Pack (LQFP) packages or two 48-pin Bump Chip Carrier (BCC) packages.

The IFR3000 and IFT3000 Rx and Tx IF/Baseband processors are designed for use in dual-mode CDMA and FM portable cellular telephones. The IFR3000 and IFT3000 devices interface between the radio-frequency (RF) section and the digital processing circuitry of the telephone.
