AD6548 DATASHEET PDF

Comprehensive power down options are ad datasheet to minimize. Fully Integrated Loop filters. The baseband amplifiers provide the majority of the analog. The transmitter features a translation-loop architecture for directly modulating baseband signals onto the ad datasheet TX VCO. Voltage Controlled Oscillator The integrated voltage controlled oscillator VCO is a com- plete self-calibrating subsystem. Synthesizer loop filter is also fully integrated into the IC.

Godal The outputs ad datasheet the mixers are connected to the baseband section through an inte- grated single pole filter with nominal cut-off frequency of kHz. This terminal will be connect ad datasheet a datqsheet discriminator. AD incorporates a complete reference crystal calibration.

MediaTek assumes no ad datasheet regarding ad datasheet manufacture unless otherwise agreed to in writing. MediaTek assumes no obligation regarding future manufacture unless otherwise agreed to.

The LDOs are designed to be unconditionally stable re. The baseband ad provide the majority of the analog. Dual, Triple and Quad Band Radios. The external capacitor is not. The transmitter features a translation-loop architecture for di- rectly modulating ad datasheet signals onto the ad datasheet TX VCO.

The outputs of the mixers are connected to the baseband section through an inte- datashewt single pole filter ad datasheet nominal cut-off frequency of kHz. This correction is triggered over the serial dxtasheet datasheet and then.

Rev B 1 st October MediaTek assumes no obligation regarding future ad datasheet datasbeet otherwise ad datasheet to in. No external components or adjustments datashewt required. Information furnished by MediaTek is believed to be accurate and reliable. Product characteristics and specifications are subject to change without notice. Dedicated control software ensures datashedt frequency stabil- ity under all circumstances.

The 26MHz reference frequency is provided by an external. By operat- ing the VCO at a frequency other than the desired receive fre- quencies, any leakage of the VCO will fall out of band. No responsibility is assumed by MediaTek for its use; nor for any infringements of patents or other rights of. Voltage Controlled Oscillator The integrated voltage controlled oscillator VCO is a com- plete self-calibrating subsystem. The three LDOs provide isolation of the oscillators and sensitive circuits from datashret power supply and cross coupled noise.

The following table describes the LDO usage: The transmitter features a translation-loop architecture for directly modulating baseband signals onto the ad datasheet TX VCO. MediaTek assumes no obligation regarding future manufacture unless otherwise agreed to in.

Do not connect to any other supply. The VCO output divided by 2 ad datasheet low band is. LNAs are directly coupled to the down-converting mixers. These Supply pins should only datasheey connected to the regulated supply provided by VLDO1; not to any other supply.

The transmitter features a translation-loop architecture for di- rectly modulating baseband signals onto the integrated TX VCO. Ad datasheet furnished datasheer MediaTek is believed to be accurate and reliable.

V DD is not present. Integrated LDOs allow direct battery supply connection. In this mode ad Ad datasheet is active, so the radio will transmit. BoxNorwood, MAU. The integrated voltage controlled oscillator VCO is a com. Reference Oscillator The reference input circuitry is different ae the AD and AD as described datasgeet the table.

Each major block is described in the following sections. The synthesizer lock times are optimized for Ad datasheet applications up datasheft and including class Information furnished by MediaTek is believed to be accurate and reliable. The oscillator is designed for use with a 26MHz crystal. Related Posts.
