Description
The SI4112-D-GT is an integrated circuit for wireless communication applications, specifically used for IF and dual-band RF synthesis. It is composed of three voltage-controlled oscillators (VCO), loop filters, reference and VCO dividers, and phase detectors. This model is programmable with a three-wire serial interface for divider and power-down settings.
Specifications and features
- Dual-band RF synthesizers: This model has two RF synthesizers: RF1 (900 MHz to 1.8 GHz) and RF2 (750 MHz to 1.5 GHz).
- IF synthesizer: This model has an IF synthesizer range of 62.5 to 1000 MHz.
- Integrated VCOs, loop filters, varactors, and resonators: The SI4112-D-GT has these components integrated into the circuit, with only a minimal number of external components required.
- Low phase noise: This characteristic helps reduce noise in the signal for better signal quality.
- Programmable power-down modes: This model has different power-down modes that can be programmed through a three-wire serial interface.
- 1 µA standby current: This model has a low standby current of only 1 µA.
- 2.7 to 3.6 V operation: The SI4112-D-GT operates within this voltage range.
- Packages: This model is available in 24-pin TSSOP and 28-lead QFN packages.
- Lead-free and RoHS compliant.
Application Scenarios
The SI4112-D-GT is ideal for the following applications:
- Dual-band communications
- Digital cellular telephones, specifically for GSM 850, E-GSM 900, DCS 1800, and PCS 1900
- Digital cordless phones
- Analog cordless phones
- Wireless local loop
