Frequently Asked Questions
What is a RAMDAC and what does the TLC34058-110FN do?
A RAMDAC (Random Access Memory Digital-to-Analog Converter) combines a color lookup table RAM with DACs to convert digital pixel data into analog RGB video signals for display output. The TLC34058-110FN stores a 256-entry palette of 24-bit colors and converts digital color indices from a graphics controller into the analog signals needed to drive CRT or other analog displays at up to 1280x1024 resolution.
What maximum display resolution and pixel clock does the TLC34058-110FN support?
The TLC34058-110FN supports a maximum pixel clock of 110MHz and is specified for display configurations up to 1280x1024 pixels. This makes it capable of driving high-resolution graphics modes used in workstation-class CRT monitors and industrial display systems that require fast pixel-rate analog video output.
What package does the TLC34058-110FN use?
The TLC34058-110FN is housed in an 84-pin PLCC (Plastic Leaded Chip Carrier) package (JESD-30 code S-PQCC-J84) with a square plastic/epoxy body. This package type was common in graphics and video ICs from the era and is compatible with standard 84-pin PLCC sockets, facilitating easy replacement and prototyping on carrier boards.
Is the TLC34058-110FN RoHS compliant?
The TLC34058-110FN carries a Pb-free code of 'No', indicating it is not a lead-free (RoHS-compliant) device. It was introduced as a legacy component and may contain lead in its solder terminations. Designers requiring RoHS-compliant alternatives for new designs should verify availability of a lead-free version or consider equivalent modern RAMDAC devices.
