ISL6323 - Monolithic Dual PWM Hybrid Controller Powering AMD SVI Split-Plane and PVI Uniplane Processors

Intersil 2008/10/06 09:33

Genaral Descroption
The ISL6323 dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6323 supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6323 features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors.
A precision uniplane core voltage regulation system is provided by a two-to-four-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers, adding flexibility in layout, reduce the number of external components in the multi-phase section. A single phase PWM controller with integrated driver provides a second precision voltage regulation system for the North Bridge portion of the processor. This monolithic, dual controller with integrated driver solution provides a cost and space saving power management solution.
For applications which benefit from load line programming to reduce bulk output capacitors, the ISL6323 features output voltage droop. The multi-phase portion also includes advanced control loop features for optimal transient response to load application and removal. One of these features is highly accurate, fully differential, continuous DCR current sensing for load line programming and channel current balance. Dual edge modulation is another unique feature,
allowing for quicker initial response to high di/dt load transients.

XR-8038A - Precision Waveform Generator

Exar 2008/10/06 09:19

GENERAL DESCRIPTION
The XR-8038A is a precision waveform generator IC capable of producing sine, square, triangular, sawtooth, and pulse waveforms, with a minimum number of external components and adjustments. The 8038A allows the elimination of the external distortion adjusting resistor which greatly improves the temperature drift of distortion, as well as lowering external parts count. Its operating frequency can be selected over eight decades of frequency, from 0.001Hz to 200KHz, by the choice of external R-C components. The frequency of oscillation is highly stable over a wide range of temperature and supply voltage changes. Both full frequency sweeping as well as smaller frequency variations (FM) can be accomplished with an external control voltage. Each of the three basic waveform outputs, (i.e., sine, triangle and square) are simultaneously available from independent output terminals.
The XR-8038A monolithic waveform generator uses advanced processing technology and Schottky-barrier diodes to enhance its frequency performance. It can be readily interfaced with a monolithic phase-detector circuit, such as the XR-2228 to form stable phase-locked circuits.

FEATURES
*Low Frequency Drift 50ppm/°C, Typical
*Simultaneous Sine, Triangle, and Square Wave Outputs
*Low Sine Wave Distortion — THD –~ 1%
*High FM and Triangle Linearity
*Wide Frequency Range 0.001Hz to 200KHz
*Variable Duty Cycle 2% to 98%
*Low Distortion Variation with Temperature

APPLICATIONS
*Precision Waveform Generation
*Sweep and FM Generation
*Tone Generation
*Instrumentation and Test Equipment Design
*Precision PLL Design
