Product details
Overview
NX5DV4885EHF,115 from NXP Semiconductors is a dual-supply 1-to-2 VGA switch IC designed for RGB, H/V-sync, and DDC signal routing in multi-display systems. It integrates three high-bandwidth SPDT RGB switches (4 Ω typical RON, 12 pF CON, 50 ps output skew), level-translating sync buffers (2.0–5.5 V input to 4.5–5.5 V output), and DDC multiplexers with over-voltage tolerant inputs. It operates across −40 °C to +85 °C and supports notebook docking stations requiring seamless VGA port switching.
For engineers reviewing the NX5DV4885EHF,115 datasheet, NX5DV4885EHF,115 pinout, NX5DV4885EHF,115 application, or NX5DV4885EHF,115 equivalent, this page delivers verified functional architecture, exact pin-level circuit roles, thermal and voltage translation constraints, and real-world use-case validation - all aligned to the Rev. 2 (2011) NXP product data sheet.
Technical Context
The NX5DV4885EHF,115 implements independent dual-supply domains: VCC(A) (2.0–5.5 V) powers RGB/SDA/SCL inputs and control logic, while VCC(B) (4.5–5.5 V) supplies RGB outputs, H1/V1 sync outputs, and DDC output clamping. Its RGB path uses low-RON/low-CON analog switches with <50 ps inter-channel skew, enabling full-bandwidth VGA signal integrity up to 850 MHz (−3 dB).
DDC switching employs active level-translating SPDTs referenced to VCC(A); output voltage is clamped to VCC(A) − Vf, requiring 3.3 V on VCC(A) for VESA-compliant I²C levels. Sync buffers translate H0/V0 (VCC(A)-referenced) to H1/V1 (VCC(B)-referenced) with 3 ns propagation delay and 15 ns enable time, supporting TTL-compatible graphics controllers.

FAQ
What is the maximum operating frequency supported by the NX5DV4885EHF,115 for VGA signals?
The NX5DV4885EHF,115 supports a −3 dB bandwidth of 850 MHz, which exceeds the fundamental frequency requirements of standard VGA (640×480 @ 60 Hz ≈ 25 MHz) and accommodates harmonics essential for sharp edge reproduction. This bandwidth ensures minimal signal degradation and preserves pixel fidelity across both output channels of the NX5DV4885EHF,115.
How does the NX5DV4885EHF,115 handle level translation between different voltage domains?
The NX5DV4885EHF,115 uses separate supply rails: VCC(A) (2.0–5.5 V) powers inputs and control logic, while VCC(B) (4.5–5.5 V) powers outputs. RGB signals switch within their respective domains, H/V-sync buffers translate from VCC(A) to VCC(B), and DDC outputs clamp to VCC(A) − Vf. This architecture enables seamless interfacing between 3.3 V graphics controllers and 5 V VGA ports in the NX5DV4885EHF,115.
Can the NX5DV4885EHF,115 be used without level translation for DDC signals?
Yes - connecting VCC(A) directly to VCC(B) disables the DDC clamping function, allowing pass-through of I²C signals without voltage translation. However, for VESA-compliant DDC operation with 3.3 V controllers driving 5 V displays, VCC(A) must be set to 3.3 V to ensure proper signal levels, as specified in the NX5DV4885EHF,115 datasheet.
What is the purpose of the break-before-make timing in the NX5DV4885EHF,115?
The NX5DV4885EHF,115 incorporates 10 ns break-before-make timing between output channels to prevent momentary short-circuiting of RGB or DDC lines during switching. This eliminates cross-talk, signal contention, and potential damage to connected VGA sources or sinks - a critical safety feature confirmed in the NX5DV4885EHF,115 functional description.
Is the thermal pad on the HVQFN24 package of the NX5DV4885EHF,115 required to be soldered?
The thermal pad on the NX5DV4885EHF,115 HVQFN24 package has no electrical requirement for soldering, but NXP recommends connecting it to GND for optimal thermal performance. If soldered, the pad must remain electrically floating or tied to GND - never to VCC(A) or VCC(B) - per the NX5DV4885EHF,115 marking and packaging documentation.
