The TSUM1PFR-LF supports LVDS (Low-Voltage Differential Signaling) panel interface formats, making it compatible with a wide range of LCD panels, from small sizes up to XGA/SXGA resolutions. 2.4 Power Management & EMI Reduction
For technicians and engineers working with displays that incorporate the TSUM1PFR-LF, the service manuals mentioned in Section VII will provide the most complete schematic-level detail for specific implementations. Tsum1pfr-lf Datasheet
The is a high-performance, cost-effective semiconductor component manufactured by MStar Semiconductor (now part of MediaTek). Primarily designed for LCD monitor applications, this integrated circuit (IC) acts as a total solution graphics processor, combining analog-to-digital conversion, scaling, and video processing in a single package. Schematic Overview & Application Diagram
| Feature | TSUM1PFR-LF | ADS1292 (TI) | MAX30003 (Analog) | |-----------------------|-------------|--------------|--------------------| | On-chip FFT | ✅ Yes | ❌ No | ❌ No | | Wake-on-pattern | ✅ Yes | ❌ No | ✅ Limited | | Supply current (active) | 1.2 mA | 0.3 mA (2ch) | 0.8 mA | | Shutdown current | 50 nA | 2 µA | 1 µA | Primarily designed for LCD monitor applications
SXGA resolutions are standard for these monitor sizes.
Because the TSUM1PFR-LF is a highly integrated IC, it is popular in several display-related applications:
The display output block uses DFR technology to maintain a stable output panel clock rate while entirely eliminating end-of-frame short-line distortion. Schematic Overview & Application Diagram
