Renesas 89H32NT24BG2ZAHL8

Overview

89H32NT24BG2ZAHL8 from Integrated Device Technology (IDT) is an evaluation board designed for the PES32NT24BG2 PCIe Gen2 32-lane, 24-port inter-domain switch. It supports x1/x2/x4/x8 link configurations, local port clocking, NTB partitioning, and DMA functionality - enabling full-system validation of high-density server and storage interconnect topologies.

For engineers reviewing the 89H32NT24BG2ZAHL8 datasheet, 89H32NT24BG2ZAHL8 pinout, 89H32NT24BG2ZAHL8 application, or 89H32NT24BG2ZAHL8 equivalent, this board delivers complete hardware access to all 32 lanes, configurable reference clocking (100/125 MHz), SMBus-managed EEPROM boot, JTAG debug, and flexible mezzanine-based expansion for PCIe endpoint, SAS, and SATA interoperability testing.

Technical Context

The 89H32NT24BG2ZAHL8 implements IDT's EB-LOGAN-23 platform, centered on the PES32NT24BG2 switch IC. It provides four 8-lane mezzanine connectors adjacent to the device, each supporting bifurcated or merged PCIe slot mapping via IDT-provided daughter cards.

Reference clocking is fully configurable: global clocks (GCLK0/GCLK1) may be sourced from host SATA, onboard ICS841484 generator (100/125 MHz), or SMA inputs; local port clocks (e.g., Port 8, Port 16) support independent 100 MHz differential sourcing via dedicated muxes and DIP switches.

Manufacturer

Integrated Device Technology, Inc. (IDT) was a fabless semiconductor company specializing in timing, memory interface, RF, and high-performance interconnect solutions before its acquisition by Renesas Electronics in 2019.

The EB-LOGAN-23 platform - including 89H32NT24BG2ZAHL8 - belongs to IDT's PCIe Inter-Domain Switch evaluation system family, engineered specifically for validating complex Gen2 switch deployments in data center servers, JBOD controllers, and PCIe fabric-based storage systems.

FAQ

What is the primary function of the 89H32NT24BG2ZAHL8 evaluation board?

The 89H32NT24BG2ZAHL8 is an IDT EB-LOGAN-23 evaluation board built to validate the PES32NT24BG2 PCIe Gen2 32-lane, 24-port switch. It enables full hardware-level testing of lane bifurcation, NTB partitioning, local port clocking, DMA, and hot-plug behavior in real server/storage environments - not a development kit with onboard firmware or software execution.

Does the 89H32NT24BG2ZAHL8 support PCIe Gen3 or higher speeds?

No. The 89H32NT24BG2ZAHL8 is designed exclusively for the PES32NT24BG2 switch, which complies only with PCIe Base Specification 2.1 (Gen2) at 5 GT/s. It does not support Gen3 (8 GT/s) or later signaling rates, nor does it include hardware or layout provisions for Gen3 signal integrity requirements.

Can the 89H32NT24BG2ZAHL8 be used with the PES32NT24AG2 switch?

Yes - the 89H32NT24BG2ZAHL8 shares identical hardware design and documentation with the EB-LOGAN-23 platform validated for both PES32NT24AG2 and PES32NT24BG2 variants. All jumper configurations, clock routing, power sequencing, and mezzanine breakout functionality apply identically to both devices.

What clock frequencies are supported for global reference inputs on the 89H32NT24BG2ZAHL8?

The 89H32NT24BG2ZAHL8 supports 100 MHz and 125 MHz global reference clock inputs (GCLK0/GCLK1), selected via SW10[2] DIP switch. Both clocks must originate from the same source and operate at identical frequencies; mixed-frequency operation is not supported and will prevent normal switch initialization.

Is there onboard firmware or software running on the 89H32NT24BG2ZAHL8?

No. The 89H32NT24BG2ZAHL8 contains no executable firmware or embedded software. Configuration is performed externally via host-based GUI tools (Windows/Linux) that communicate over PCIe to read/write PES32NT24BG2 registers and generate binary images for SMBus-connected EEPROMs - the board itself is purely hardware.
