CDK3400/CDK3401

10-bit, 100/150MSPS, Triple Video DACs

f e a t u r e s

General Description

nꢀ

10-bit resolution

CDK3400/3401 products are low-cost triple D/A converters that are tailored

to ﬁt graphics and video applications where speed is critical. Two speed

grades are available: CDK3400 at 100MSPS and CDK3401 at 150MSPS.

nꢀ

150 megapixels per second

±0.1% linearity error

Sync and blank controls

TTL-level inputs are converted to analog current outputs that can drive

25-37.5Ω loads corresponding to doubly-terminated 50-75Ω loads. A sync

1.0V_ppvideo into 37.5Ω or 75Ω load

Internal bandgap voltage reference

Double-buffered data for low distortion

TTL-compatible inputs

current following SYNC input timing is added to the IO output. BLANK

will override RGB inputs, setting IO , IO and IO currents to zero when

BLANK = L. Although appropriate for many applications, the internal 1.235V

reference voltage can be overridden by the V input.

Low glitch energy

REF

Single +5V power supply

Few external components are required, just the current reference resistor,

current output load resistors, and decoupling capacitors.
