Overview
The PI2LVD412ZHE is a bidirectional multiplexer/demultiplexer switch designed for Low Voltage Differential Signaling (LVDS). It features four differential channels with a 2:1 configuration, controlled by a single enable pin. The device operates within a supply voltage range of +1.5V to +2.0V and supports data rates 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.
Applications
- Routing multiple Low Voltage Differential Signals at high-speed data rates
- High-speed digital signal multiplexing and demultiplexing
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The ZHE designation indicates a Pb-free and Green compliant component in a Tape/Reel format. Confirm that the manufacturer has discontinued this part number before initiating procurement, as availability may be limited or subject to last-time buy constraints.
Selection Notes
Select this component for applications requiring precise routing of differential signals with strict timing requirements. The low bit-to-bit skew ensures signal integrity in high-speed environments. Ensure the design accommodates the 1.5V to 2.0V supply voltage range and the thermal characteristics of the 42-contact TQFN package for reliable operation.
Part Context
This component belongs to the Pericom Semiconductor family of LVDS-compliant switches, now under Diodes Incorporated. It is engineered specifically for differential signaling applications where low skew and high isolation are critical. The device simplifies system design by integrating multiple channels into a single compact package, reducing board space and component count.
Replacement Considerations
The PI2LVD412ZHE is listed as End-of-Life (EOL). Verify if the PI2LVD412ZHEX variant offers identical functionality and packaging. Consult official substitution guides from Diodes Incorporated for qualified alternatives that meet the same electrical and mechanical specifications.
