Power Sequencing Guideline

TI ASIC I/O design allows either the core supply (VDD) or the I/O supply (VDDS) to be powered up(2) for an

indefinite period of time while the other power supply is not powered up, if all of these constraints are met:

•

Chip is within all maximum ratings and recommended operating conditions.

•

Have followed all warnings about exposure to maximum rated and recommended conditions, particularly

junction temperature. These apply to power transitions as well as normal operation.

•

Bus contention while VDDS is powered up must be limited to 100 hours over the projected lifetime of the

device.

•

Bus contention while VDDS is powered down may violate the absolute maximum ratings.

However, it is generally good practice to power up VDD, VDDSHV, and VDDS all within 1 second of each other.

Application Information

The GC533x reference design includes the following additional transmit/receive signal chain components:

•

TMS320C6748 digital signal processor (DSP) and DPD adaptation software

•

DAC3283 16-bit 800-MSPS, dac348X, or DAC5682 16-bit, 1-GSPS DAC (transmit path)

•

CDCE72010 clock generator

•

TRF3720 300-MHz to 4.8-GHz quadrature modulator with integrated wideband PLL/VCO

•

TRF370317 0.4-GHz to 4-GHz quadrature modulator

•

ADS41B49 14-bit, 250-MSPS ADC (and other options; feedback path)

•

AMC7823 analog monitoring and control circuit with GPIO and SPI

•

PGA870 wideband programmable gain amplifier

•

ADS42b49 14-bit dual 250-MSPS receive or complex feedback ADC (and other options; RX path)

MPU Interface Guidelines

The following section describes the hardware interface between the recommended microprocessor and the

GC533x. The GC533x interface is an EMIF asynchronous interface.

(2)

A supply bus is powered up when the voltage is within the recommended operating range. It is powered down when it is below that

range, either stable or in transition.
