MAX3845DVI/HDMI 2:4 TMDS Fanout Switch and Cable Driver | Linear | 3 | Active | The MAX3845 is a TMDS® 2-to-4 fanout switch and cable driver for multimonitor distribution of DVI™ or HDMI™ signaling up to 1.65Gbps. Both inputs and outputs are standard TMDS signaling as per DVI and HDMI standards. Because TMDS links are "point-to-point", buffering is required for fanout applications.Four DVI/HDMI TMDS outputs are provided for fanout distribution. Each TMDS output can be independently sourced from either input or can be turned off. Each TMDS input or output is composed of four differential channels that can be arbitrarily assigned to the three data signals and the 1/10th-rate clock. The data rate depends on resolution, but it can vary from 250Mbps (VGA) to 1.65Gbps (UXGA or 1080p/60).Typical applications include multiroom display of the same video source or industrial/commercial signage applications such as airport monitors or trading room floor displays. The MAX3845 includes selectable output preemphasis that extends output cable reach up to an additional 7m.For DDC switching, use the companion MAX4814E 2:4 low-resistance CMOS crosspoint switch. DDC switching is not required for applications that connect DDC to one reference monitor only.The MAX3845 can be configured to create a 2 x 8 or 4 x 4 switch (see theTypical Operating Circuitdiagrams located in the full data sheet).The MAX3845 is available in a 14mm × 14mm, 100-pin TQFP-EP package and operates over the -10°C to +85°C temperature range.ApplicationsDigital Signage and Industrial DisplayDVI/HDMI Crosspoint SwitchesDVI/HDMI Distribution AmplifiersHome A/V ReceiversPC Monitor Distribution |
MAX385Precision, Low-Voltage, SPST CMOS Analog Switch | Integrated Circuits (ICs) | 5 | Active | The MAX381/MAX383/MAX385 are precision, low-voltage analog switches. The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open. The single-pole double-throw MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance (less than 35Ω), guaranteed to match to within 2Ω between channels and to remain flat over the specified analog signal range (4Ω max). They also offer low leakage (less than 250pA at +25°C and less than 2.5nA at +85°C) and fast switching (turn-on time less than 175ns and turn-off time less than 100ns).The MAX381/MAX383/MAX385 are fabricated with Maxim's low-voltage silicon-gate process for high system accuracy. Design improvements guarantee extremely low charge injection (< 5pC) and low power consumption (< 10µW).These monolithic switches operate with a single positive supply (+3V to +15V) or with split supplies (±3V to ±8V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading.ApplicationsAudio-Signal RoutingBattery-Powered ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXSample-and-Hold CircuitsTest Equipment |

MAX38642.5Gbps, +3V to +5.5V, Wide Dynamic Range Transimpedance Preamplifier | Instrumentation, Op Amps, Buffer Amps | 2 | Obsolete | The MAX3864 is a transimpedance preamplifier for applications in SDH/SONET systems operating up to 2.5Gbps. It features 490nA (typ) input-referred noise, 2.0GHz bandwidth, and 2mA input overload.The MAX3864 operates from a single +3.0V to +5.5V supply. It includes an integrated low-frequency compensation capacitor, as well as a filter connection that provides positive bias through a 750Ω resistor to VCC. These features save external components, simplifying design and assembly into a TO-46 header with a photodiode.The MAX3864 has a typical optical dynamic range of -24dBm to 0dBm using a PIN photodetector.Applications2.5Gbps ATM ReceiversAPD Preamplifier ReceiversPIN Preamplifier ReceiversRegenerators for SDH/SONETSDH/SONET Transmission Systems |
