PCI930PBK

Overview

The PCI930 is a 3-to-1 Zoomed Video (ZV) switch designed as a companion chip for the TI PCI1220/1221 PC Card controllers. It functions as a multiplexer for the 23 pins defined in the PCMCIA zoomed video interface, routing video and audio data from three sources to a single output. The device features a low-power 3.3-V core logic with 5-V tolerant I/Os. It operates within a commercial temperature range of 0°C to 70°C. The component is housed in a small form factor 128-pin TQFP package.

Feature Summary

Supports up to three ZV sources with software-programmable switching via registers
First two inputs are controlled by PCI1220/1221 control signal outputs
Includes status bits indicating ZV activity for potential fourth source switching
Fully compliant with the PCMCIA Zoomed Video Standard

Applications

Zoomed video switching for PC Card sockets A and B
External buffering for multiple ZV sources
Routing ZV data to VGA controllers and audio CODECs

Procurement Notes

Verify the specific revision level against the datasheet SCPS018B revised December 1997. Confirm that the 128-pin TQFP package matches the target PCB footprint. Ensure the design accommodates the 3.3V core voltage and 5V tolerant I/O requirements for the zoomed video streams.

Selection Notes

Select this component when interfacing with TI PCI1220/1221 controllers or when a 3:1 multiplexer for PCMCIA zoomed video signals is required. Consider the 128-pin TQFP package constraints and the need for external pullup resistors on specific control pins to define default states and precedence.

Part Context

This part is an analog/video switch specifically engineered for legacy PCMCIA zoomed video applications. It serves as a bridge between PC Card sockets and downstream display or audio processing components, handling both YUV video data and PCM audio signals simultaneously.
