Product details
Overview
PI2EQX6804-ANJEX from Pericom Semiconductor is a 6.5 Gbps, 4-port, 8-lane SAS2.0/SATA3.0/XAUI ReDriver™ with programmable receiver equalization and transmitter emphasis, 1.2 V ±0.05 V single supply, and 50 Ω I/O termination. It reconditions high-speed serial signals across backplanes and low-quality cables in enterprise storage interconnects.
For engineers reviewing the PI2EQX6804-ANJEX datasheet, PI2EQX6804-ANJEX pinout, PI2EQX6804-ANJEX application, or PI2EQX6804-ANJEX equivalent, key selection criteria include differential lane count (8), equalization/emphasis adjustability, I²C + pin-strapped configuration, OOB support, and LFBGA-100 package compatibility with high-density server PCB layouts.
Technical Context
The PI2EQX6804-ANJEX implements dual-stage signal conditioning: adaptive CML receiver equalization compensates for pre-driver channel loss (e.g., FR4 trace attenuation), while post-driver emphasis (peaking) restores high-frequency content degraded by interconnect dispersion. Each of its eight differential lanes operates independently with configurable gain and peaking profiles.
It supports full out-of-band (OOB) signaling required for SAS/SATA link initialization and negotiation, and integrates mux/demux and channel loop-back modes for system-level debug and compliance validation. Power-down mode reduces quiescent current to <100 µA per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 6.5 Gbps per lane - enables SAS2.0, SATA3.0, and XAUI compliance without protocol translation. |
| Lane Count | 8 differential lanes (4 ports) - supports dual 4-lane SAS domains or mixed SAS/SATA fan-out topologies. |
| Supply Voltage | 1.2 V ±0.05 V - tight tolerance ensures stable biasing of CML output drivers and low-jitter operation. |
| I/O Termination | 50 Ω on-chip differential termination - eliminates external resistors, reduces BOM count, and maintains impedance continuity. |
| Configuration | Pin-strapped + I²C (3.3 V tolerant) - allows factory-set defaults and runtime reconfiguration without level-shifting circuitry. |
| Power Down | Hardware-controlled standby mode - cuts per-lane supply current to <100 µA, enabling dynamic power gating in idle links. |
Pinout & Package
Package: 100-contact, 9 mm × 9 mm, 0.8 mm pitch Lead-Free Fine-Pitch Ball Grid Array (LFBGA) with exposed thermal pad. RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core supply input | 1.2 V power for analog/IO circuitry; requires local 100 nF + 10 µF decoupling. |
| VDDIO | I/O supply input | 3.3 V tolerant I²C interface supply; independent from core VDD for mixed-voltage system integration. |
| SDA/SCL | I²C bidirectional bus | Supports multi-drop configuration up to 4 devices; pull-up required externally. |
| PD# | Active-low power-down control | Hardware assertion forces all lanes into ultra-low-power state; asynchronous to data path. |
| EQ[2:0] | Equalization select bits | 3-bit parallel strap sets receiver CTLE boost (0–15 dB) in discrete steps for channel loss compensation. |
| EM[2:0] | Emphasis select bits | 3-bit parallel strap configures transmitter high-frequency peaking (0–9 dB) to counter post-cable dispersion. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable CTLE equalization | 7-level receiver boost (0–15 dB) adapts to varying pre-driver channel loss without firmware overhead. |
| Adjustable transmitter emphasis | 7-level high-frequency peaking (0–9 dB) restores signal integrity after long or lossy interconnects. |
| Mux/Demux capability | Enables flexible routing between ASIC and switch fabric or cable connectors without external logic. |
| Full OOB support | Preserves SAS/SATA handshake sequences (e.g., COMINIT, COMWAKE) for reliable link training and recovery. |
| Channel loop-back mode | Per-lane internal feedback path simplifies production test and real-time eye diagram validation. |
Applications
| Enterprise Server Backplane Interconnect | SAS Expander Module Signal Extension |
|---|---|
Use Scenario: Extending SAS2.0 signals from host HBA to multiple drive bays across a 12-layer FR4 backplane with >20 dB loss at 3.25 GHz. IC Role / Device Role / Timing Role: ReDriver™ placed mid-path to open closed eye diagrams; provides adaptive equalization pre- and emphasis post-device. Use Value: Enables reliable 6.5 Gbps operation over 30+ cm backplane traces where raw ASIC outputs fail compliance testing. | Use Scenario: Fan-out from a single SAS controller to 4× SAS3-capable drives using legacy SAS2.0 infrastructure. IC Role / Device Role / Timing Role: Signal conditioner inserted between expander ASIC and SFF-8087 connectors to restore jitter margin and amplitude. Use Value: Maintains link stability under temperature variation and connector wear, reducing drive dropouts by >90% in stress testing. |
| High-Density Storage Enclosure | XAUI-to-SATA Protocol Bridge System |
Use Scenario: Driving 8× SATA3.0 SSDs from a single SoC in a 2U rackmount chassis with tight spacing and shared ground planes. IC Role / Device Role / Timing Role: 4-port ReDriver™ managing simultaneous SATA lanes with independent EQ/EM tuning per port. Use Value: Eliminates need for separate AC-coupling capacitors and termination resistors, saving 24 passives per port. | Use Scenario: Converting XAUI (4×3.125 Gbps) to 4× SATA3.0 (6 Gbps) in network-attached storage with legacy PHYs. IC Role / Device Role / Timing Role: Protocol-transparent signal repeater preserving XAUI encoding while meeting SATA electrical specs. Use Value: Avoids full protocol translation ICs; reduces latency by 1.8 ns and power by 320 mW vs. bridge-based solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed serial signal reconditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB544 | USB3.1 Gen1-specific (5 Gbps), no SAS/SATA OOB support, integrated USB switch logic. | Limited to USB host-peripheral topologies; lacks SAS link training and COMINIT handling. | Select only for USB-native systems requiring integrated switching; not suitable for SAS/SATA infrastructure. |
| Diodes AP1212 | Fixed 6 dB emphasis, no receiver equalization, 4-lane only, no I²C interface. | Requires pre-characterized channels; cannot adapt to variable backplane loss or aging effects. | Use where cost sensitivity outweighs signal adaptability; unsuitable for field-upgradable or multi-platform designs. |
Compared with TI TUSB544 and Diodes AP1212, the PI2EQX6804-ANJEX uniquely combines SAS2.0/SATA3.0/XAUI protocol transparency, full OOB support, and independent per-lane equalization + emphasis-enabling robust, field-tunable signal integrity in multi-standard storage backplanes.

FAQ
What is the function of the EQ[2:0] and EM[2:0] pins?
EQ[2:0] sets 7-level receiver equalization gain (0–15 dB) to compensate for pre-ReDriver channel loss; EM[2:0] configures 7-level transmitter emphasis (0–9 dB) to restore high-frequency content post-ReDriver. Both are static strap inputs sampled at power-up and do not require clocking or timing constraints.
Does PI2EQX6804-ANJEX support SAS3.0 (12 Gbps)?
No. The PI2EQX6804-ANJEX is rated for up to 6.5 Gbps and meets SAS2.0, SATA3.0, and XAUI specifications only. It does not support the 12 Gbps data rate, enhanced OOB signaling, or SAS3.0-specific equalization profiles required for SAS3.0 compliance.
Can the device operate with only I²C configuration, without pin strapping?
Yes. All configuration registers-including EQ/EM settings, power-down control, and mux/demux routing-are accessible via I²C. Pin strapping provides default values at power-on reset but is optional; full functionality remains available through software control after initialization.
Is the LFBGA-100 package compatible with standard reflow profiles?
Yes. The PI2EQX6804-ANJEX LFBGA-100 package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak temperature 260°C, 60-second duration above 217°C), including typical 8-zone convection ovens used in high-volume PCB assembly.
