Analog Devices Inc. AD8190ACPZ-R7

Overview

AD8190ACPZ-R7 from Analog Devices is a 2:1 HDMI/DVI switch IC with integrated input equalization and output pre-emphasis, designed for high-speed TMDS signal routing in consumer A/V systems. It supports data rates up to 1.65 Gbps, handles pixel clocks from 25 MHz to 165 MHz, features four TMDS channels per link plus four auxiliary bidirectional channels, and enables reliable 1080p operation over 20-meter 24 AWG HDMI cables.

For engineers reviewing the AD8190ACPZ-R7 datasheet, AD8190ACPZ-R7 pinout, AD8190ACPZ-R7 application, or AD8190ACPZ-R7 equivalent, this page delivers verified electrical parameters, I²C-configurable equalization/pre-emphasis settings, thermal performance at −40°C to +85°C, LFCSP package layout guidance, and real-world switching behavior in HDTV receiver and projector designs.

Technical Context

The AD8190ACPZ-R7 implements a quad-channel 2:1 switch core for HDMI/DVI TMDS links, with independent programmable equalization (6 dB or 12 dB) on all eight high-speed inputs and selectable pre-emphasis (0–6 dB) on outputs. Its dual-supply architecture separates analog (AVCC/AVEE), digital (DVCC/DVEE), termination (VTTI/VTTO), and auxiliary (AMUXVCC) domains to minimize noise coupling.

Switching is controlled via I²C interface using two user-selectable slave addresses (0b1001000 or 0b1001001), with register-based configuration of source selection (Input A/B), auxiliary channel routing (AUX_A/AUX_B), output disable, and termination enable/disable. The device supports wire-OR array expansion through high-impedance output disable mode.

Key Specifications

Pinout & Package

AD8190ACPZ-R7 uses a 56-lead, 8 mm × 8 mm LFCSP package with an exposed thermal paddle (ePAD) that must be connected to AVEE (0 V) for thermal compliance. Pin functions are validated per Analog Devices Rev. 0 datasheet Figure 3 and Table 4.

FAQ

What is the maximum HDMI cable length supported by AD8190ACPZ-R7 at 1080p resolution?

The AD8190ACPZ-R7 supports up to 20 meters of 24 AWG HDMI cable at 1080p/60Hz when configured with 12 dB input equalization. This capability is validated per HDMI 1.2a receiver eye mask compliance and assumes standard reference cable insertion loss of −15 dB at relevant frequencies. Performance varies with actual cable quality and ambient temperature.

Does AD8190ACPZ-R7 require external termination resistors for TMDS signals?

No, AD8190ACPZ-R7 includes fully configurable 50 Ω on-chip terminations for both inputs (VTTI) and outputs (VTTO). External termination is optional and used only when higher current drive or specific impedance tuning is required. Internal terminations are enabled by default after reset.

Can AD8190ACPZ-R7 switch HDCP-encrypted content between sources?

Yes, AD8190ACPZ-R7 is HDCP standard compatible and transparently passes HDCP authentication and encrypted video streams. Its auxiliary channel switching supports full DDC bus routing-including EDID reads and writes-enabling seamless HDCP handshaking between any selected source and downstream display.

How is the I²C address configured for AD8190ACPZ-R7?

The AD8190ACPZ-R7 I²C slave address is 0b100100X, where X is determined by the logic level on the I2C_ADDR pin: tied to 0 V for 0b1001000 (0x48), or to 3.3 V for 0b1001001 (0x49). This allows two AD8190ACPZ-R7 devices to share the same I²C bus without address conflict.

What thermal design considerations apply to AD8190ACPZ-R7 in a 4-layer PCB?

For thermal compliance, the AD8190ACPZ-R7's exposed paddle (ePAD) must be soldered to a solid AVEE (0 V) copper plane with ≥6 thermal vias (0.3 mm diameter) connecting to inner ground layers. With this layout on a JEDEC-standard 4-layer board, θJA remains at 27°C/W, limiting junction temperature to ≤115°C at 936 mW max power dissipation and +85°C ambient.
