PD672X/30/32/33 — ZV Port Implementation 1.0 Introduction The PD6710, PD6722, and PD6729 are single-chip PCMCIA interface controllers capable of controlling one or two PCMCIA or compact Flash sockets, respectively. They are designed for use in embedded applications and notebook systems where reduced form factor and low power consumption are critical design objectives. Current typical application examples include: Routers Integrated access devices Access network servers DSLAMs PBXs

PD672X/30/32/33 — ZV Port Implementation 2.0 Overview This application note discusses system design considerations associated with the implementation of the ZV (Zoomed Video) Port when using the PD6722/’29/’30, or PD6832 controller devices. Intended to assist the system designer, this document highlights how various aspects of the PC Card relate to the ZV Port implementation. Since the ZV Port implementation overlaps PC Card, graphics, and audio technologies, consulting with appropriate appl

PD672X/30/32/33 — ZV Port Implementation Note that ZV Port implementation is likely to vary depending on the platform; the Socket Services software must be customized to address these variances. Controlling the OE (output enable) inputs of the external buffers depends upon specific hardware design and software needs to be aware of specifics, such as the I/O Port addresses. When the PC Card Multimedia mode is used, Intel recommends that the ZV Port pins be connected as shown in Tables 1–3 for

PD672X/30/32/33 — ZV Port Implementation A buffer circuit placed between the PC Card bus and the VGA video port reduces the trace length to lower the loading effect. The ZV Port standard requires that the length of the trace between the PC Card connector and the buffer (if used) must be less than two inches. Buffers are also needed to support ZV Port PC Cards in either socket. In a full implementation of the ZV Port, multiple PC Card slots can be used to implement the ZV Port. This implies t

PD672X/30/32/33 — ZV Port Implementation 5.0 Dedicated Socket Approach to ZV Port Implementation Figure 2 shows a solution using the PD6722/’29/’30/’6832 Controller and the GD7XXX Super VGA controller to support a single dedicated ZV Port slot. This simple implementation does not require any external buffer or glue logic; the only limitation is that one socket must be dedicated to the ZV Port. Also, depending upon the audio controller used, a buffer may be required between the PC Card bus a

PD672X/30/32/33 — ZV Port Implementation 6.0 Buffer Implementation for Audio DAC A buffer solution to isolate the audio controller when the socket is not configured in ZV Port mode is shown in Figure 3. This illustrates how to control the buffer enable; if the GD7XXX is used, then one of the GPO pins can control the buffer enable. Figure 3.

If using the GD7XXX, two of the GPO pins can control the buffer output enables. Since there is only one V-Port, a ZV Port PC Card can be inserted in either Socket A or Socket B. Figure 4.

PD672X/30/32/33 — ZV Port Implementation 8.0 Layout Guidelines The VGA controller, the PC Card (PCMCIA) Controller, and the PC Card Sockets must be in close proximity to one another. This requirement is particularly important when the PD6832 or PD6833 device is used along with the ZV Port for Card bus implementation. According to tests conducted by PCMCIA ZV Port subcommittee, the stubs to the GD7548 device or any other VGA controller must be no longer than two inches. As shown in Figure 4 o
