Product details
Overview
IP4787CZ32 from Nexperia is an HDMI 2.0-compliant ESD protection and interface management IC for sink devices, integrating TMDS line protection (±12 kV contact ESD), DDC/CEC bidirectional buffering, hot plug drive, and 5 V power management. It supports 6.0 Gbps TMDS bit rate, UHD 4k@60 Hz, and maintains 100 Ω differential impedance on TMDS lines with <0.6 pF effective capacitance.
For engineers reviewing the IP4787CZ32 datasheet, IP4787CZ32 pinout, IP4787CZ32 application, or IP4787CZ32 equivalent, this device addresses HDMI receiver-side signal integrity, ESD robustness, cable compatibility with high-capacitance cables (>700 pF), and system-level power sequencing in consumer and computing displays.
Technical Context
The IP4787CZ32 implements Transmission Line Clamping (TLC) on all eight TMDS lanes to minimize impedance discontinuities without PCB pre-compensation, achieving 90–110 Ω differential input impedance and <0.6 pF effective shunt capacitance per channel. Its dual-supply architecture uses VCC(5V0) (4.5–6.5 V) for connector-side functions and VCC(SYS) (1.1–3.63 V) for system-side level shifting.
DDC and CEC paths feature integrated pull-up resistors (47 kΩ for DDC_CON, 26 kΩ for CEC_CON, 3.65 kΩ for DDC_SYS), capacitive decoupling between system and connector sides, and active redriving - enabling reliable operation with non-compliant HDMI cables up to 6 nF DDC load. The ACTIVE pin controls CEC-only standby mode (1.2 mW) versus full operation (50 mW).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Protection | ±12 kV contact per I/O (IEC 61000-4-2 Level 4), applied to all 24 external I/O pins including TMDS, DDC, CEC, HOTPLUG, UTILITY |
| TMDS Data Rate | 6.0 Gbps (supports HDMI 2.0 UHD 4k@60 Hz), verified via eye diagrams at 227 MHz, 297 MHz, and 148.5 MHz pixel clocks |

| Capacitive Load Handling | Drives DDC/CEC cables with >700 pF capacitance (up to 6 nF demonstrated), decoupling ASIC-side capacitance from cable-side load |
| Supply Voltages | VCC(5V0): 4.5–6.5 V (connector-side power); VCC(SYS): 1.1–3.63 V (system-side level shift); enables 1.2 V–3.3 V ASIC interfacing |
| Power Consumption | 1.2 mW in CEC Standby mode (ACTIVE = LOW); 50 mW in full operation (DDC @ 100 kHz, CEC @ 1 kHz, 50% duty) |
| Operating Temperature | −25 °C to +85 °C ambient, validated across static/dynamic parameters and ESD robustness |
Pinout & Package
IP4787CZ32 is housed in a 5 mm × 5 mm × 0.85 mm HVQFN32 (SOT617-3) thermally enhanced leadless package with exposed thermal pad. Pin assignment follows flow-through routing optimized for HDMI signal integrity and minimal crosstalk.
| Pin/Terminal | Circuit Role | Design Meaning |

| 25, 29 | CEC_CON, CEC_SYS | CEC signal path with 26 kΩ pull-up (CON), 10 kΩ pull-up (SYS), and leakage-limited (<0.1 µA) isolation in power-down |
| 26, 30 | ESD_BYPASS, ENABLE_LDO | ESD bias reference node and 5 V LDO enable control - allows flexible sourcing of HDMI_5V0_CON from either VCC(5V0) or HDMI connector |
| 13, 16 | HDMI_5V0_CON, UTILITY_CON | 5 V input from HDMI connector (with overvoltage/overcurrent limiting) and utility line ESD protection (e.g., HEAC) |
| 28 | ACTIVE | Standby mode control: LOW enables CEC-only operation (1.2 mW); HIGH enables full functionality (DDC, TMDS, HOTPLUG, UTILITY) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI sink interface protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD12S521 | Single 5 V supply only; no VCC(SYS) level-shifting; 4-channel TMDS (no CK lane support); 8 kV ESD rating | Limited to 1080p/60 Hz systems; cannot support full HDMI 2.0 8-lane TMDS or 1.2 V ASIC interfaces | Choose for cost-sensitive 1080p designs where level-shifting and 4k support are unnecessary |
| ON Semi ESD7574MUTAG | Discrete 8-channel ESD array only; no DDC/CEC buffering, no hot plug drive, no power management | Requires external buffers, level shifters, and HPD circuitry - increases BOM count and layout complexity | Choose only when full integration is not required and discrete protection suffices for legacy HDMI 1.4 systems |
Compared with TPD12S521 and ESD7574MUTAG, IP4787CZ32 delivers full HDMI 2.0 sink-side integration - combining ESD, buffering, power management, and hot plug in one HVQFN32 package - reducing PCB area by >40% and eliminating six external components typically needed with discrete alternatives.

FAQ
What HDMI standards does the IP4787CZ32 support?
The IP4787CZ32 supports HDMI 2.0 and all backward-compatible standards including HDMI 1.4 and DVI. It is validated for 6.0 Gbps TMDS bit rate, enabling UHD 4k@60 Hz display modes, and meets HDMI CTS TID 7-11 requirements for hot plug and power management functionality.
How does the IP4787CZ32 handle high-capacitance HDMI cables on the DDC lines?
The IP4787CZ32 uses bidirectional DDC buffering with capacitive decoupling between system and connector sides. Its integrated 47 kΩ pull-up on DDC_CON and 3.65 kΩ pull-up on DDC_SYS, combined with active redriving, enables reliable operation with cables exhibiting up to 6 nF DDC capacitance - far exceeding the HDMI 50 pF limit.
What is the role of the ACTIVE pin on the IP4787CZ32?
The ACTIVE pin on the IP4787CZ32 controls operating mode: LOW enables CEC-only standby mode (1.2 mW), keeping CEC functional while placing all other outputs in high-impedance state; HIGH enables full operation (DDC, TMDS, HOTPLUG, UTILITY). Strapping ACTIVE to VCC(SYS) also protects ASIC I/Os during power-down.
Does the IP4787CZ32 require external components for basic operation?
No - the IP4787CZ32 requires only a single external capacitor for operation, as all pull-ups, pull-downs, ESD structures, and bias networks are integrated. External components are eliminated for DDC, CEC, TMDS, and hot plug circuits, reducing BOM count and PCB footprint versus discrete solutions.
What is the thermal package type and size of the IP4787CZ32?
The IP4787CZ32 uses an HVQFN32 (SOT617-3) package measuring 5 mm × 5 mm × 0.85 mm with an exposed thermal pad. This thermally enhanced leadless package supports efficient heat dissipation in space-constrained HDMI sink designs while enabling fine-pitch routing for high-speed TMDS signals.
