PD672X/30/32/33 — ZV Port Implementation Application Note 5 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 sy...

PD672X/30/32/33 — ZV Port Implementation 6 Application Note 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, ...

PD672X/30/32/33 — ZV Port Implementation Application Note 7 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 specifi...

PD672X/30/32/33 — ZV Port Implementation Application Note 9 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 ...

PD672X/30/32/33 — ZV Port Implementation 10 Application Note 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, th...

PD672X/30/32/33 — ZV Port Implementation Application Note 11 7.0 ZV Port Implementation for Socket A and B Figure 4 shows the ZV Port support for socket A and B. 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 i...

PD672X/30/32/33 — ZV Port Implementation Application Note 15 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 th...
