SKY74038: 2.6 GHz/800 MHz Dual Fractional-N/lnteger-N

Frequency Synthesizer

Applications

Description

Skyworks SKY74038 is a complete, low-power 2.6 GHz/800 MHz

dual frequency synthesizer. The device provides both Radio

Frequency (RF) channels and Intermediate Frequency (IF)

channels. Fractional-N operation offers low phase noise, fast

settling time, and low spurious tones for RF channels. A standard

integer-N division is used for IF channels.

• Multi-slot GSM/DCS

• PCS/W-CDMA

• Portable communication systems

• Dual-mode cellular telephone systems

• Spread spectrum receivers

• Wireless LAN systems

The three-wire serial interface provides programmable control of

the frequency synthesizer to support dual-conversion

transceivers.

• Wireless routers and WLL systems

• SATCOM receivers

The SKY74038 is available as a 20-pin Thin Shrink Small Outline

Package (TSSOP) (-13 option) or as a Pb-free 20-pin TSSOP (-21

option). The device package and pin configuration are shown in

Figure 1. A functional block diagram of the SKY74038 is shown in

Figure 2.
