DS90CP22MX-8/NOPB is a type of logic-signal switch, multiplexer, and decoder. It is a high-performance CMOS differential line receiver used in both industrial and consumer applications, such as imaging systems and multimedia equipment. The device is designed to connect two levels of differentially driven sources in a single package, enabling two-level LVDS or two-level RS-232/RS-485 signaling. It provides an easy-to-use interface for designers that require 1:1, 2:1 and 4:1 switching from one source to multiple destinations.

The DS90CP22MX-8/NOPB implements two high-performance, full-range differential line receivers that can accept signals with TTL, LVCMOS, or high-end LVDS input levels. Each of the receivers features a selectable input buffer impedance of 50 ohms (Zin=60Ω) or 100 ohms (Zin=80Ω). It also features robust power and ground pins, which enable high-performance switching at up to 500 MBaud data rate when the supply voltage is between 1.8 and 3.3 VCC.

The device supports a number of features to improve system performance. One of those features is its adjustable threshold voltage, which allows designers to select an appropriate level for either LVDS or LVCMOS input signals. The adjustable threshold voltage can be adjusted by using an external voltage, enabling the user to vary the power consumption in order to further reduce power consumption. The adjustable threshold voltage also helps ensure a reliable transmission connection, even when the signal levels of the source devices vary.

The DS90CP22MX-8/NOPB is designed to accept differential input signals. This allows it to operate as both a multiplexer and a decoder. The device can switch between one, two, and four input signals, allowing it to act as a multiplexer or decoder to connect two differentially driven sources. This provides an easy-to-use interface for designers who need to switch from one source to multiple destinations.

The DS90CP22MX-8/NOPB also includes an on-chip automatic calibration circuit, which helps provide an accurate switching between the differential inputs. This auto-calibration circuit reduces the number of external components needed, which reduces the overall BOM cost for the application. In addition, the device provides high-speed operation and low power consumption, with typical power consumption as low as 90 μA at 5 VCC.

The DS90CP22MX-8/NOPB operates over a temperature range of -40 to +85°C, making it suitable for industrial applications and consumer applications in high-temperature environments. Its durable construction also ensures reliable operation over the long term. As a result, the device is an ideal choice for designers who need an efficient and reliable solution for LVDS and LVCMOS signal switching.
