description
The TLC5602x devices are low-power, ultra-high-speed video, digital-to-analog converters that use the
LinEPIC 1-µm CMOS process. The TLC5602x converts digital signals to analog signals at a sampling rate
of dc to 20 MHz. Because of high-speed operation, the TLC5602x devices are suitable for digital video
applications such as digital television, video processing with a computer, and radar-signal processing.
The TLC5602C is characterized for operation from 0°C to 70°C. The TLC5602M is characterized over the full
military temperature range of –55°C to 125°C.

APPLICATION INFORMATION
The following design recommendations benefit the TLC5602 user:
D
Physically separate and shield external analog and digital circuitry as much as possible to reduce system
noise.
D
Use RF breadboarding or RF printed-circuit-board (PCB) techniques throughout the evaluation and
production process.
D
Since ANLG GND and DGTL GND are not connected internally, these terminals need to be connected
externally. With breadboards, these ground lines should connect to the power-supply ground through
separate leads with proper supply bypassing. A good method is to use a separate twisted pair for the analog
and digital supply lines to minimize noise pickup.
Use wide ground leads or a ground plane on the PCB layouts to minimize parasitic inductance and
resistance. The ground plane is the better choice for noise reduction.
D
ANLG VDD and DGTL VDD are also separated internally , so they must connect externally. These external
PCB leads should also be made as wide as possible. Place a ferrite bead or equivalent inductance in series
with ANLG V
DD
and the decoupling capacitor as close to the device terminals as possible before the ANLG
V
DD
and DGTL VDD leads are connected together on the board.
D
Decouple ANLG VDD to ANLG GND and DGTL VDD to DGTL GND with a 1-µF and 0.01-µF capacitor,
respectively, as close as possible to the appropriate device terminals. A ceramic chip capacitor is
recommended for the 0.01-µF capacitor.
D
Connect the phase compensation capacitor between COMP and ANLG GND with as short a lead-in as
possible.
D
The no-connection (NC) terminals on the small-outline package should be connected to ANLG GND.
D
Shield ANLG VDD, ANLG GND, and A OUT from the high-frequency terminals CLK and D7 –D0. Place
ANLG GND traces on both sides of the A OUT trace on the PCB.
