Product details
Overview
PCI7610GHK from Texas Instruments is a four-function, 33-MHz PCI Local Bus Revision 2.3-compliant integrated controller combining PC Card (CardBus/16-bit) socket control, Smart Card/SD/MMC/Memory Stick interface, and dual-port IEEE 1394a-2000 OHCI PHY/Link-Layer controller. It delivers 132-MBps burst throughput, supports S100/S200/S400 data rates (100/200/400 Mbits/s), and operates with 1.8-V core / 3.3-V I/O logic. It enables high-performance FireWire™-capable PC Card expansion in mobile computing systems.
For engineers reviewing the PCI7610GHK datasheet, PCI7610GHK pinout, PCI7610GHK application, or PCI7610GHK equivalent, key selection considerations include its dual 1394a-2000 port compliance, ExCA register compatibility with Intel 82365SL–DF, PCI power management (D0–D3 states), 24.576-MHz crystal-based clocking, and integrated Smart Card/SD/MMC/Memory Stick socket interface.
Technical Context
The PCI7610GHK implements four distinct PCI functions: Function 0 handles PC Card socket control with hot insertion/removal support and subtractive decoding; Function 1 provides dedicated interface logic for Smart Card, SD/MMC, or Memory Stick sockets; Function 2 integrates full IEEE 1394a-2000 OHCI-compliant PHY and link-layer controller with two independent cable ports, each with separate TPBIAS and line condition monitoring; Function 3 enables firmware loading into internal program RAM via I/O-mapped interface.
Its PHY layer uses an internal PLL driven by a 24.576-MHz crystal to generate 393.216-MHz reference and 49.152-MHz LLC synchronization clocks, enabling data-strobe encoding at S100/S200/S400 speeds. The device supports advanced 1394a features including multispeed concatenation, arbitration acceleration, fly-by concatenation, port disable/suspend/resume, and ultralow-power sleep mode with automatic power-down of inactive ports and link-layer during suspend.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PC Card and IEEE 1394 host controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2046B | USB 2.0 hub controller (not 1394); no PC Card or Smart Card interface; 48-MHz crystal; 1.8-V/3.3-V dual supply | Targets USB peripheral expansion-not FireWire or memory card reader applications | Select only if migrating from 1394 to USB-based connectivity and abandoning PC Card form factor |
| PCI7421ZHK | TI-recommended replacement; BGA-256 package; enhanced 1394a-2000 PHY with lower jitter; added PCIe interface option; same 1.8-V core | Designed for next-gen mobile platforms requiring higher integration density and improved signal integrity | Preferred for new designs where long-term supply and updated 1394 timing performance are critical |
Compared with PCI7610GHK, TUSB2046B lacks 1394 functionality and PC Card support entirely, making it unsuitable for FireWire expansion; PCI7421ZHK offers pin-compatible upgrade path with improved 1394 PHY jitter and PCIe option, but requires PCB redesign due to 256-pin vs. 209-pin BGA.

FAQ
What is the primary function of the PCI7610GHK in a PC Card system?
The PCI7610GHK serves as a four-function PCI-to-PC Card bridge: Function 0 controls the PC Card socket (16-bit/CardBus), Function 1 manages Smart Card/SD/MMC/Memory Stick interfaces, Function 2 implements dual-port IEEE 1394a-2000 OHCI PHY/LLC, and Function 3 loads firmware. Its role is to unify these capabilities in a single chip for mobile expansion cards, eliminating discrete controllers and reducing layout complexity. The PCI7610GHK enables seamless integration of FireWire, memory card readers, and legacy PC Card support in notebook peripherals.
Does the PCI7610GHK support both 3.3-V and 5-V PC Cards?
Yes, the PCI7610GHK supports any combination of 16-bit and CardBus cards powered at either 5 V or 3.3 V through internal voltage sensing and level translation. Its PC Card socket controller (Function 0) implements auto-sensing circuitry that detects card voltage requirements and configures I/O buffers accordingly-enabling hot insertion and removal of mixed-voltage cards without external components. This capability is confirmed in the SLLA251 datasheet and ensures compatibility with legacy 5-V and modern 3.3-V PC Cards.
What crystal frequency is required for the PCI7610GHK's 1394 PHY operation?
The PCI7610GHK requires a 24.576-MHz fundamental-mode crystal connected to its XIN/XOUT pins to drive the internal PLL that generates the 393.216-MHz reference and 49.152-MHz LLC synchronization clocks. This specific frequency is mandated to achieve exact S100/S200/S400 bit rates (100/200/400 Mbits/s) and maintain IEEE 1394a-2000 timing compliance. The datasheet explicitly states that an external clock may substitute the crystal, but the 24.576-MHz value is non-negotiable for accurate 1394 data-strobe encoding-critical for PCI7610GHK's dual-port FireWire functionality.
Is the PCI7610GHK pin-compatible with the Intel 82365SL–DF controller?
Yes, the PCI7610GHK implements ExCA-compatible registers mapped in memory or I/O space and is explicitly designed to be register-compatible with the Intel 82365SL–DF controller. This allows direct software replacement in existing PC Card driver stacks without modifications to OS-level services or BIOS. However, physical pinout differs due to the PCI7610GHK's BGA-209 package versus the 82365SL–DF's PQFP package-so PCB layout changes are required despite functional and register-level compatibility. The datasheet confirms this relationship for seamless migration paths.
What power management features does the PCI7610GHK provide for battery-powered systems?
The PCI7610GHK supports PCI D0–D3 power states per the PCI Bus Power Management Interface Specification 1.1, including automatic device power-down during suspend, inactive port power-down, and ultralow-power sleep mode. It also implements IEEE 1394a-2000 power-down features such as link-layer power management and node power class signaling for system-level energy control. These capabilities enable significant power savings in notebook applications-verified in the SLLA251 datasheet-and allow the PCI7610GHK to meet Intel Mobile Power Guideline requirements for extended battery life.
