power plane. The analog power plane should be connected
to the board’s normal V
CC
power plane at a single point
though a low-resistance ferrite bead, such as a Ferroxcube
5659065-3B, Fair-Rite 2743001111, or TDK BF45-4001. The
ferrite bead provides resistance to switching currents,
improving the performance of HMP8116. A single 47
μ
F
capacitor should also be used between the analog power
plane and the ground plane to control low-frequency power
supply ripple.
If a separate linear regulator is used to provide power to the
analog power plane, the power-up sequence should be
designed to ensure latchup will not occur. A separate linear reg-
ulator is recommended if the power supply noise on the V
AA
pins exceeds 200mV.
Analog Signals
Traces containing digital signals should not be routed over,
under, or adjacent to the analog output traces to minimize
crosstalk. If this is not possible, coupling can be minimized
by routing the digital signals at a 90 degree angle to the ana-
log signals. The analog input traces should also not overlay
the V
AA
power plane to maximize high-frequency power sup-
ply rejection.
EVALUATION BOARD
HMPVIDEVAL/ISA
The HMPVIDEVAL/ISA evaluation board allows connecting
the HMP8116 into a PC ISA slot for evaluation. It includes
the HMP8115 NTSC/PAL decoder, 3MB of VRAM, and a
NTSC/PAL encoder. The board accepts composite or S-
video input and displays video on a standard TV. The ISA
bus and evaluation software allow easy performance evalua-
tion of the HMP8116 using tools such as the Tektronix
VM700 video test system.
