description
The 3-to-1 ZV switch is a companion chip to the PCI1220/1221 PC Card controllers; however, it can be used
in other applications where multiple ZV sources require external buffering. The ZV switch is a 3:1 multiplexer
for the 23 pins defined in the PCMCIA zoomed video interface. The ZV interface includes both the video and
audio data as defined by the
Zoomed Video Specification.
The three ZV source interfaces are referred to as A, B, and C. ZV sources A and B are intended for use with
the PCI1220/1221 PC Card zoom video outputs. The third source, C, may be from a variety of external ZV
sources.
An advanced CMOS process is used to achieve low system-power consumption.

NOTES:
1. The PC Card interface is 68 pins for CardBus and 16-bit PC Cards. In zoomed-video mode 23 pins are used for routing the
zoomed video signals too the VGA controller.
2. Control pin for third ZV source (Can Use GPO From PCI1220).

TYPE
FUNCTION
RESET
116
I
Chip reset. When asserted (driven low), the chip three-states all outputs. In addition, the PCI930
checks for a pullup resistor on the A/B STAT pin as denoted under ZV_xx terminal function.
A/B_STAT
48
I
PC Card ZV (Socket 0 or 1) active. This input indicates that either the A or B source from the PC Card
controller is active. This signal is used with A/B_SEL to determine which socket ZV source drives the
ZV_xx outputs. The A or B source can be passed to ZV_xx if the C source is either of lower precedence,
or is not sourcing valid ZV data, as indicated by the C_STAT signal.
A/B_SEL
49
I
Socket A/B select. When this pin and A/B_STAT are high, the PC Card socket A ZV data is valid. When
this pin is low, and the A/B_STAT input is high, the PC Card socket B ZV data is valid. This input has
no meaning if the A/B_STAT input is low.
C_STAT
50
I
C source status. When this input is high, the ZV source from interface C is valid, and can be driven
to the ZV_xx outputs. The C source can be passed to ZV_xx if the A and B sources are either of lower
precedence, or A or B is not sourcing valid ZV data.
ZV_OE
114
I
ZV output I/F enable. When this terminal is low, the ZV switch drives the ZV_xx terminals.
ZV_STAT
113
O
ZV output status. This terminal is driven high when the ZV switch drives the ZV_xx terminals.
ZV_xx State
N/A
N/A
When a pullup resistor is present on the A/B_STAT pin during RESET, then the ZV_xx interface is
three-stated if the ZV_xx interface is inactive. During the default state, no pullup resistor, a reset drives
the ZV_xx interface to a logic low state when inactive.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
3. Applies for external input and bidirectional buffers. VI > VCC does not apply to fail-safe terminals. ZV terminals are measured with
respect to VCCS. The limit specified applies for a DC condition.
4. Applies for external output and bidirectional buffers. VO > VCC does not apply to fail-safe terminals. ZV terminals are measured with
