The DS90CP04 1.5 Gbps 4x4 LVDS Crosspoint Switch is a digital cross-point switch produced by National Semiconductor Corporation. It uses Low Voltage Differential Swing (LVDS) technology for low power, high speed and low noise.
The DS90CP04 is a 4x4 digital cross‑point switch that uses Low Voltage Differential Swing (LVDS) technology for low‑power, high‑speed operation. It features a non‑blocking architecture that allows any input to be connected to any output, with fully differential data paths for low noise.
Key features include a single +2.5 V supply, a small 6 × 6 mm LLP‑32 package, serial control with read‑back capability, and a wide input common‑mode voltage range that works with LVDS, LVPECL, and 2.5 V‑CML drivers. The device supports data rates up to 1.5 Gbps with low jitter and skew.
| Data Rate | 1.5 Gbps |
|---|---|
| Supply Voltage | +2.5 V |
| Package | LLP‑32 (6 × 6 mm) |
| Number of Channels | 4 × 4 |
| Maximum Serial Clock Frequency | 100 MHz |
The device operates from a single +2.5 V supply.
It has four differential inputs and four differential outputs, forming a 4 × 4 switch matrix.
The switch supports data rates up to 1.5 Gbps.
It can be configured via a simple serial control interface or a configuration select port using the MODE pin.
