PMAC2 PCI Hardware Reference Manual
2 Introduction
Option 5xF: CPU Speed Options
• Option 5CF: 80MHz DSP563xxx CPU (160MHz 56002 equivalent)
• Option 5EF: 160MHz DSP563xxx CPU (320MHz 56002 equivalent)
• Option 5AF: 40MHz DSP563xx CPU (80MHz 56002 equivalent) Default configuration provided
automatically if no CPU option ordered.
Option 6: Extended Servo Algorithm
The standard PID servo algorithm with feedforward and notch filter is suitable for most applications.
Systems with difficult dynamics, especially with significant flexibility, may require a more powerful
servo algorithm, such as the Extended Servo Algorithm (ESA).
Option 7: Plate Mounting
• Option 7 provides a mounting plate connected to the PMAC2 PCI with standoffs. It is used to install
the PMAC2 PCI in standalone applications.
Option 8: High-Accuracy Clock Crystal
The PMAC2 PCI has a clock crystal (component Y1) of nominal frequency 19.6608MHz (~20MHz).
The standard crystal’s accuracy specification is +/-100 ppm.
• Option 8A provides a nominal 19.6608MHz crystal with a +/-15 ppm accuracy specification.
Option 10: Firmware Version Specification
Normally the Turbo PMAC2 PCI is provided with the newest released firmware version. A label on the
U10 flash memory IC on the CPU board shows the firmware version loaded at the factory.
• Option 10 provides for a user-specified firmware version.
Option 12: Analog-to-Digital Converters
• Option 12 permits the installation of 8 or 16 channels of on-board multiplexed analog-to-digital
converters. 1 or 2 of these converters are read every phase interrupt. The analog inputs are not
optically isolated, and each can have a 0 – 5V input range, or a +/-2.5V input range, individually
selectable.
• Option 12 provides an 8-channel 12-bit A/D converter. The key components on the board are U28
and connector J1.
• Option 12A provides an additional 8-channel 12-bit A/D converter. The key component on the board
is U29.
Option 16: Battery-Backed Parameter Memory
The contents of the standard memory are not retained through a power-down or reset unless they have
been saved to flash memory first. Option 16 provides supplemental battery-backed RAM for real-time
parameter storage that is ideal for holding machine state parameters in case of an unexpected power-
down. The battery is located at component BT1.
• Option 16 provides a 16k x 24 bank of battery-backed parameter RAM in components U6, U9, and
U15 on the CPU board.
