A CableCARD is a PCMCIA, Type II PC Card. The CableCARD is used in place of a set top cable decoder box, and plugs into the HD TV to provide the cable decoder function. Other terms include S-Card [Single-Stream CableCard] or Digital Cable Ready [DCR].
The M-Card or CableCard operating in the M-Mode allows for Multi-Stream data. A Multi-stream CableCARD is a single CableCARD that is capable of decrypting multiple channels, thereby allowing consumers to record one channel while simultaneously watching
another channel.
The PC Card PCMCIA specification defines both the Electrical and
Physical specifications for a 68 pin interface residing in one of 3 form
factors, which differ only in thickness;
Type I: dimensions 3.3mm x 85.6mm x 54.0mm (TxLxW), Version 2.1
allows the length to increase 50mm to 135mm
Type II: dimensions 5.0mm x 85.6mm x 54.0mm (TxLxW), Version 2.1
allows the length to increase 50mm to 135mm
Type III: dimensions 10.5mm x 85.6mm x 54.0mm (Tall x Length x
Width)
The implementation of this spec based on the ISA bus is termed the PC Card with a
8/16 bit data bus, 26 address lines, and no bus mastering. PC Card-16
cards use an 8-bit or 16-bit interface that operates at ISA bus speeds
(10 MHz) using an ISA-like asynchronous protocol. All of the PCMCIA
implementations use Plug and Play and have Hot Swapping capabilities. The
16-bit PCMCIA 'PC Card' will operate up to a maximum of 20MBps, or
160Mbps. The actual throughput will depend on the minimum cycle
time and the transfer mode and will never reach the maximum
throughput rates. Back to the main PCMCIA Bus page.
Flash memory cards vs. PC Card format.
CableCard is a PCMCIA slot and PCMCIA card, a tuner card that can be inserted into a slot in the TV to replace a cable set-top box.
Some TV descriptions indicate the term CableCard, while others indicate Digital Cable Ready [see below]. I was only able to find a few HDTV units from Hitachi which came with a CableCard slot. I see a few from Sony too. The CableCard allows the user to plug cable directly into a TV set without the need for a set-top box [STB]. CableCard slots may also be found on Divigal Video Recorders [DVR] |

The PC Card uses a 68 pin connector, with two rows of 34 pins, with 0.05
inch spacing [1.27mm]. Female pins are used on the card side, male pins
on the system end.
The power and ground pins are longer than the signal
lines, allowing them to make connect first.
