Diodes Incorporated PI3VDP3212ZLEX

Overview

PI3VDP3212ZLEX from Diodes Incorporated is a DisplayPort™ 1.2-compliant 2-lane, 1:2 mux/demux IC with dedicated 1:2 switching for DP_HPD and DP_Aux signals, supporting data rates up to 5.4 Gbps. It features -1.7 dB insertion loss at 2.7 GHz, 4.7 GHz -3dB bandwidth, and <7 ps bit-to-bit skew-enabling low-attenuation routing between one DisplayPort source and two sinks or two sources to one display.

For engineers reviewing the PI3VDP3212ZLEX datasheet, PI3VDP3212ZLEX pinout, PI3VDP3212ZLEX application, or PI3VDP3212ZLEX equivalent, key selection criteria include differential channel bandwidth, HPD/Aux path isolation, high-speed crosstalk (-25 dB @ 5.4 Gbps), VDD tolerance (3.3 V ±10%), and TQFN-32 package compatibility in space-constrained video interface designs.

Technical Context

The PI3VDP3212ZLEX implements independent control logic for high-speed lanes (D0±/D1±), AUX±, and HPD paths via three digital inputs: SEL (high-speed path A/B), AUX_SEL (AUX/HPD path A/B), and OE (global enable/power-down). All I/Os enter high-impedance state when OE = HIGH.

Its architecture supports simultaneous 2-lane DP signal routing with separate sideband channel switching-ensuring full compliance with DisplayPort 1.2 timing, skew (<35 ps channel-to-channel), and signal integrity requirements including return loss (-16 dB @ 2.7 GHz) and off-isolation (-25 dB @ 5.4 Gbps).

FAQ

What is the maximum supported data rate for the high-speed differential lanes?

The PI3VDP3212ZLEX supports DisplayPort 1.2 High Bit Rate 2 (HBR2) at 5.4 Gbps per lane. Its 4.7 GHz -3dB bandwidth and -1.7 dB insertion loss at 2.7 GHz ensure compliant eye opening and jitter margin under real-world PCB trace conditions. This is verified per DS41905 Rev 1-2 test conditions at TA = –40°C to +85°C and VDD = 3.3 V ±10%.

Can the AUX and HPD paths be routed to different ports than the high-speed lanes?

Yes. The AUX_SEL pin independently controls routing of AUX± and HPD signals, allowing them to be assigned to Port A while high-speed lanes go to Port B-or vice versa. This enables asymmetric configurations such as dual-source selection with shared AUX/EDID access or split HPD monitoring, as defined in the truth table on page 2 of DS41905.

Does the device require external termination resistors for DP lanes?

No. The PI3VDP3212ZLEX is designed for use with standard 100 Ω differential PCB traces and does not require external termination. Its internal RON_HS of 10 Ω (typical) is optimized to match typical source/load impedances without added components-reducing layout complexity and maintaining signal integrity up to 5.4 Gbps.

How does the OE pin affect power consumption and signal integrity?

When OE is HIGH, all I/Os enter high-impedance state and internal circuitry powers down, reducing quiescent current to near-zero (ICC < 1 µA). Signal integrity is preserved because no DC path exists between ports-eliminating leakage-induced crosstalk or false HPD assertions during standby, as confirmed in the "Truth Table" and "Maximum Ratings" sections of DS41905.
