General Description The MAX4885 integrates high-bandwidth analog switches and level-translating buffers to implement a complete 1:2 or 2:1 multiplexer for VGA signals. The device provides switching for RGB, display data chan- nel (DDC), and horizontal and vertical synchronization (HSYNC, VSYNC) signals. A low-noise charge pump with internal capacitors provides a boosted gate-drive voltage to improve performance of the RGB switches. In the 1:2 multiplexer mode, HSYNC/VSYNC inputs fea- ture level-shifting buffers to support low-voltage CMOS or standard TTL-compatible graphics controllers. In the 2:1 multiplexer mode, the output buffers for the HSYNC/VSYNC inputs are disabled, allowing bidirec- tional signaling. In both modes, DDC signals are volt- age-clamped to an external voltage to provide level translation and protection. The MAX4885 features a 5µA shutdown mode and is ESD protected to ±8kV Human Body Model (HBM) on externally routed pins. The MAX4885 is specified over the extended (-40°C to +85°C) temperature range, and is available in the 32- pin, 5mm x 5mm TQFN package.

M A X 4 8 8 5 Complete VGA 1:2 or 2:1 Multiplexer _______________________________________________________________________________________ 9 Detailed Description The MAX4885 integrates high-bandwidth analog switches and level-translating buffers to implement a complete 1:2 or 2:1 multiplexer for VGA signals. The device provides switching for RGB, HSYNC, VSYNC, and DDC signals. A low-noise charge pump with inter- nal capacitors provides a boosted gate-drive voltage to improve performance of the RGB switches. The device provides two modes of operation: 1:2 and 2:1. In 1:2 mode (M = 0), the HSYNC and VSYNC inputs feature level-shifting buffers to support TTL out- put logic levels from low-voltage graphics controllers. These buffered switches may be driven from as little as +2.0V up to +5.5V. In 2:1 mode (M=1), the output buffers for the HSYNC and VSYNC signals are dis- abled. In both modes, RGB signals are routed with the same high-performance analog switches, and DDC sig- nals are voltage clamped to a diode drop less than VCL. Voltage clamping provides protection and com- patibility with DDC signals and low-voltage ASICs. In keyboard/video/mouse (KVM) applications, VCL is nor- mally set to +5V because low-voltage clamping is not required, as specified by the VESA standard. Drive EN logic high to shut down the MAX4885. In shut- down mode, supply current is reduced to 5µA and all switches are high impedance, providing high-signal rejection. The RGB, HSYNC, VSYNC, and DDC switches are ESD protected to ±8kV by the Human Body Model. RGB Switches The MAX4885 provides three SPDT high-bandwidth switches to route standard VGA R, G, and B signals (see Table 1). A boosted gate-drive voltage is generat- ed by an internal charge pump to improve performance of the RGB switches. The R, G, and B analog switches are identical, and any of the three switches can be used to route red, green, or blue video signals. The RGB switches function with reduced performance with the charge pump disabled. Charge Pump A low-noise charge pump with internal capacitors pro- vides a doubled voltage for driving the RGB analog switches. Noise voltage from the charge pump is less than 50µVP-P. The noise level is more than 80dB below the signal level, making the charge pump suitable for Pin Description (continued) PIN NAME FUNCTION 18 H2 Horizontal Sync I/O 19 V2 Vertical Sync I/O 22 V1 Vertical Sync I/O 23 H1 Horizontal Sync I/O 24 B1 RGB Analog I/O 25 G1 RGB Analog I/O 26 R1 RGB Analog I/O 27 DDCB1 DDC I/O 28 DDCA1 DDC I/O 31 M Mode Select.

Outstanding supplier! Heisener is on a very short list of suppliers I can recommend. From stock, pricing, ease of ordering and great service, they get it all.

I like this way to add a project, choose existing project to add components. I use this method frequently to keep track of my projects. Thanks Heisener!
