Analog Devices Inc. AD9396KSTZ-100

Overview

AD9396KSTZ-100 from Analog Devices is a dual-interface video capture IC integrating an 8-bit, 150 MSPS triple analog-to-digital converter and a DVI 1.0 receiver with HDCP 1.1 support. It captures RGB/YPbPr component video up to 1080p/720p and SXGA (1280 × 1024 @ 80 Hz), delivers RGB/YCbCr outputs, and operates from 1.8 V/3.3 V supplies in a 100-lead Pb-free LQFP package.

For engineers reviewing the AD9396KSTZ-100 datasheet, AD9396KSTZ-100 pinout, AD9396KSTZ-100 application, or AD9396KSTZ-100 equivalent, key selection considerations include its dual analog/DVI input capability, 330 MHz analog bandwidth, HDCP 1.1 authentication/decryption, programmable clamping and sync processing, and 100 MSPS maximum conversion rate for the -100 variant.

Technical Context

The AD9396KSTZ-100 implements two independent signal paths: an analog front end with three 8-bit ADCs (150 MSPS max, 330 MHz full-power bandwidth) and a DVI-compatible TMDS receiver supporting up to 150 MHz pixel clock with intrapair skew tolerance of one full clock cycle. Its on-chip PLL generates pixel clocks from 12 MHz to 100 MHz (for -100 variant) with <700 ps p-p jitter at 100 MHz.

It integrates full sync processing for composite sync and sync-on-green (SOG), RGB-to-YCbCr 2-way color space conversion, Macrovision® detection, and dual-channel 2:1 muxing for analog inputs. HDCP 1.1 compliance is enabled via dedicated DDC and master serial ports interfacing with external EEPROM for key storage.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog input frequency supported by the AD9396KSTZ-100?

The AD9396KSTZ-100 supports a full-power analog bandwidth of 330 MHz, enabling accurate digitization of video signals with high-frequency content such as sharp edges and fine text. This bandwidth directly supports all HDTV formats up to 1080p and SXGA (1280 × 1024 @ 80 Hz), ensuring minimal signal distortion during capture. The 330 MHz specification is measured under standard conditions (VDD = 3.3 V, DVDD = PVDD = 1.8 V).

Does the AD9396KSTZ-100 support HDCP 1.1 authentication and decryption?

Yes, the AD9396KSTZ-100 fully supports HDCP 1.1 protocol including authentication of the video receiver, decryption of encoded TMDS data, and renewability of keys during active transmission. This functionality relies on dedicated I²C interfaces (DDCSCL/DDCSDA for transmitter communication and MCL/MDA for external EEPROM key storage), and is confirmed in the device's functional block diagram and General Description section.

What are the power supply requirements for the AD9396KSTZ-100?

The AD9396KSTZ-100 requires four distinct supply rails: VD = 3.3 V ± 3% (analog/terminators), VDD = 1.8–3.3 V (digital outputs), PVDD = 1.8 V ± 5% (PLL), and DVDD = 1.8 V ± 5% (digital logic). Supply sequencing must ensure VD and VDD never fall more than 300 mV below DVDD, and DVDD never exceeds VD or VDD by more than 300 mV-per Absolute Maximum Ratings Table 3.

Can the AD9396KSTZ-100 operate with both analog and digital inputs simultaneously?

Yes, the AD9396KSTZ-100 is explicitly designed for concurrent analog and digital operation: its analog interface digitizes RGB/YPbPr signals via triple 8-bit ADCs, while its DVI 1.0 receiver processes TMDS data streams-all within a single monolithic IC. The functional block diagram shows parallel signal paths feeding into shared output formatting and timing logic, enabling true dual-source video routing without external multiplexing.

What is the purpose of the RTERM pin on the AD9396KSTZ-100?

The RTERM pin (Pin 46) sets the internal 50 Ω TMDS termination impedance by connecting an external 500 Ω ±1% resistor to ground. This configuration ensures optimal signal integrity on high-speed DVI inputs (Rx0±, Rx1±, Rx2±, RxC±) by matching characteristic line impedance and minimizing reflections. Leaving RTERM unconnected disables internal termination, which is not recommended for DVI compliance.
