KAI-2093 Image Sensor
Evaluation Timing
Specification
12-bit 20 MHz AFE
Altera Code Version Description
The Altera code described in this document is intended for
use in the KSC−1000 Timing Boar. The code is developed
specifically for use with the following system configuration:

The 3F5051 Timing Generator Board features the
KSC−1000 Timing Generator chip. The KSC−1000
provides all of the signals necessary for an imaging system
using Full Frame (KAF) or Interline (KAI) family of image
sensors. It also provides the signals necessary for operation
of two analog front-end (AFE) chips, enabling independent
optimization of the AFE chips for dual channel readout
devices.
ALTERA CODE FEATURES/FUNCTIONS
The Altera Programmable Logic Device (PLD) serves as
a state machine, which performs a variety of functions.
Three basic functions are required, common to all CCD
image sensor configurations: serial input steering, AFE
default programming, and KSC−1000 default
programming. In addition, certain other functions specific to
the KAI−2093 Image Sensor are implemented.
Serial Input Steering
The 3-wire serial interface enters the Timing Board
through the DIO Interface connector, and is routed to the
PLD. The Altera PLD decodes the addressing of the serial
input, and steers the datastream to the correct device.
The serial input must be formatted so that the Altera PLD
can correctly decode and steer the data to the correct device.
The serial interface can be used to dynamically change the
operating conditions of the AFE or KSC−1000 chips by
reprogramming the appropriate registers. Reprogramming
these registers through the serial interface will have no effect
on the default settings that are automatically programmed
into these devices on power-up or board reset.
