Evaluation Kits
The HMP8190EVAL1 is a small (index card size) printed
circuit board containing the encoder, voltage references and
bypassing, analog output filters, and input/output
connectors. The board allows the encoder’s operation and
performance to be observed and measured.
The HMP8190EVAL1 board has a 50 pin, two row receptacle
which allows connection into an existing system. The
connector provides access to all of the encoder’s digital
inputs and outputs.
The HMP8156EVAL2 is the Intersil designed mother board
for the HMP8190EVAL1. The mother board is a standard
size PC add in card with an ISA bus interface and application
software. The HMP8156EVAL2 kit is a complete system
which allows demonstrating all of both encoders’ operating
modes. It has analog video inputs for composite, S-video,
and component RGB signals. The analog signals are
converted/decoded to the digital domain and input to the
encoder. The board also provides a 3 megabyte video RAM
for image capture and display and a BT.656 connector and
interface.
For simpler operation, the HMP8190EVAL1 may also be
driven by external power supplies, a BT.656 signal
generator, and a PC parallel port. The evaluation kit includes
application software to program the part using its I
2
C bus
connected to the printer port. The board includes the
standard 25 pin BT.656 connector and interface.
