FMS3110/3115

Triple Video D/A Converters

3 x 10 bit, 150 Ms/s

Features

Description

• 10-bit resolution

• 150 megapixels per second

• ± 0.1% linearity error

FMS3110/3115 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:

• Sync and blank controls

100 Ms/s

150 Ms/s

• 1.0V p-p video into 37.5Ω or 75Ω load

• Internal bandgap voltage reference

• Double-buffered data for low distortion

• TTL-compatible inputs

• Low glitch energy

• Single +5 Volt power supply

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 current following SYNC input timing

is added to the I

output. BLANK will override RGB

inputs, setting I , I and I currents to zero when

BLANK = L. Although appropriate for many applications

the internal 1.235V reference voltage can be overridden by

OG OB OR

Applications

• Video signal conversion

– RGB

the V

input.

REF

– YC C

B R

– Composite, Y, C

Few external components are required, just the current

reference resistor, current output load resistors, and

decoupling capacitors.

• Multimedia systems

• Image processing

• True-color graphics systems (1 billion colors)

• Broadcast television equipment

• High-Deﬁnition Television (HDTV) equipment

• Direct digital synthesis

Package is a 48-lead LQFP. Fabrication technology is

CMOS. Performance is guaranteed from 0 to 70°C.
