Overview
The PI2LVD412ZHEX is a bidirectional multiplexer/demultiplexer switch designed for Low Voltage Differential Signaling (LVDS). It features four differential channels with a 2:1 configuration, enabling high-speed data routing. The device operates within a supply voltage range of +1.5V to +2.0V and supports signal switching beyond 3.6 Gbps. Key electrical parameters include a maximum bit-to-bit skew of 10 ps, an on-resistance flatness of 1 ohm, and a quiescent power supply current of 200 µA. It provides -77 dB off-isolation and -68 dB crosstalk at 10 MHz. The component is housed in a 42-contact TQFN package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports LVDS signal switching at high-speed data rates exceeding 3.6 Gbps with minimal attenuation.
- Features low insertion loss of -2.88 dB at 2.9 Gbps for efficient signal transmission.
- Provides high channel-to-channel noise isolation with low crosstalk and off-isolation specifications.
- Utilizes a single enable pin configuration for simplified control of the multiplexing function.
Applications
- Routing multiple Low Voltage Differential Signals in high-speed data systems.
- Signal distribution in LVDS-compliant electronic interfaces.
- High-speed data path switching where low bit-to-bit skew is critical.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The ZH suffix indicates a 42-contact TQFN package. Confirm RoHS compliance status through the manufacturer's latest product change notifications or datasheet revisions before procurement.
Selection Notes
Select this component when designing circuits requiring bidirectional LVDS switching with strict skew requirements. Ensure the system power supply remains within the 1.5V to 2.0V range. Verify that the thermal dissipation capabilities of the 42-contact TQFN package are sufficient for the application's power budget.
Part Context
This part belongs to the PI2LVD412 series of LVDS compliant switches manufactured by Diodes Incorporated (formerly Pericom Semiconductor). It is specifically engineered for applications demanding high bandwidth and low signal distortion in differential signaling environments.
Replacement Considerations
