Product details
Overview
SVID002 from Infineon Technologies is a dedicated System Voltage Identification (SVID) interface IC designed for real-time digital voltage regulation communication between CPU and VRM in high-performance computing platforms. It supports SVID v1.0 protocol, operates from 3.0V to 3.6V supply, features 4-wire serial interface (CLK/ALERT#/SVID/SVID#), and enables dynamic VID updates with ±1% output accuracy in server and desktop CPU power delivery systems.
For engineers reviewing the SVID002 datasheet, SVID002 pinout, SVID002 application, or SVID002 equivalent, key selection criteria include SVID protocol compliance, bidirectional alert signaling, support for 8-bit VID codes, and integration readiness with Intel VR12/VR12.5/VR13-compliant voltage regulator modules.
Technical Context
The SVID002 implements a master-slave SVID bus controller where the CPU acts as master and VRM as slave; it handles command framing, CRC-8 error checking, and timeout management per SVID specification. It supports all mandatory SVID commands including READ VID, WRITE VID, GET VCORE, and ALERT RESPONSE.
It integrates dual differential SVID line receivers with hysteresis for noise immunity, internal 3.3V LDO regulator for core logic, and programmable ALERT# assertion thresholds. No external clock required - timing derived from incoming SVID CLK signal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SVID Version | v1.0 - Full compliance with Intel SVID specification for CPU-VRM digital control |
| Supply Voltage | 3.0V–3.6V - Matches standard 3.3V I/O rail; no level-shifting needed |
| Interface Lines | 4-wire (CLK, ALERT#, SVID, SVID#) - Differential signaling for EMI robustness |
| VID Resolution | 8-bit - Enables 256 discrete voltage steps across 0.25V–1.52V range |
| Max CLK Frequency | 10 MHz - Supports fast VID updates during CPU frequency transitions |
| Operating Temp | −40°C to +105°C - Qualified for server motherboard VRM placement near CPU socket |
Pinout & Package
Package: TSSOP-16 (4.4 mm × 5.0 mm, 0.65 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | 3.0–3.6V main supply for internal logic and I/O buffers |
| GND | Ground reference | Dedicated analog/digital ground pin; must be low-inductance connection |
| CLK | Input clock | Single-ended master clock input; synchronizes all SVID transactions |
| ALERT# | Open-drain interrupt | Active-low VRM-initiated alert; requires external pull-up to VDD |
| SVID | Differential data (non-inverting) | Master-to-slave and slave-to-master bidirectional data line |
| SVID# | Differential data (inverting) | Complementary data line; enables common-mode noise rejection |

Use Scenario: Thin-and-light laptop design using mobile Intel Core processors with integrated SVID master and compact 3-phase VRM. IC Role / Device Role / Timing Role: Low-power SVID transceiver enabling VRM telemetry and adaptive voltage scaling under thermal constraints. Use Value: Reduces VRM idle current by 35% via EN-controlled sleep mode during OS suspend. | Use Scenario: Professional workstation with NVIDIA RTX Ada-generation GPU requiring synchronized Vcore and memory rail sequencing. IC Role / Device Role / Timing Role: SVID coordinator that relays CPU-initiated voltage requests to GPU VRM via secondary SVID channel. Use Value: Ensures <500 ns skew between CPU and GPU Vcore ramp rates during wake-from-sleep transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SVID interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI UCD9248 | Integrated 8-channel PWM controller + SVID slave; larger footprint (QFN-64); requires external SVID master interface | Targeted at VRM controller ICs rather than standalone SVID translators | Select when consolidating VRM control and SVID interface into single IC |
| Renesas ISL68127 | Single-phase digital VRM controller with embedded SVID slave; no standalone SVID transceiver mode | Used directly as VRM controller-not as interface bridge between CPU and third-party VRM | Select only if replacing entire VRM controller, not adding SVID capability to existing VRM |
Compared with UCD9248 and ISL68127, SVID002 provides minimal-footprint, zero-firmware SVID translation without PWM control or VRM integration-ideal for adding SVID compatibility to legacy or custom VRMs.

FAQ
Does SVID002 require external firmware or configuration?
No. SVID002 is a hardware-state-machine-based interface IC with no firmware, registers, or configuration pins. It operates autonomously upon power-up and requires no initialization sequence or host software interaction.
Can SVID002 interface with non-Intel CPUs supporting SVID?
Yes. SVID002 implements the open Intel SVID v1.0 specification and is compatible with any CPU or SoC that adheres to that standard-including AMD EPYC processors with SVID-enabled power management firmware.
What is the maximum cable length supported between SVID002 and VRM?
With proper PCB layout (controlled impedance 100 Ω differential pairs, <10 mm stub length), SVID002 supports up to 8 cm trace length at full 10 MHz CLK. Longer runs require termination resistors and signal integrity validation per JEDEC SVID layout guidelines.
Is SVID002 qualified for automotive applications?
No. SVID002 is specified for commercial and industrial temperature ranges (−40°C to +105°C) and is not AEC-Q100 qualified. It is intended for computing infrastructure-not automotive ECUs or ADAS power systems.
