Analog Devices Inc. AD9397KSTZ-150

Overview

AD9397KSTZ-150 from Analog Devices is a DVI 1.0-compliant digital video receiver IC with integrated HDCP 1.1 decryption, supporting up to 150 MHz pixel clock, 1080p/720p HDTV formats, and RGB ↔ YCbCr color space conversion. It operates with dual supply rails (3.3 V VD / 1.8 V DVDD), delivers 24-bit parallel RGB/YCbCr outputs, and targets front-end video interface applications in flat-panel displays and projectors.

For engineers reviewing the AD9397KSTZ-150 datasheet, AD9397KSTZ-150 pinout, AD9397KSTZ-150 application, or AD9397KSTZ-150 equivalent, key selection considerations include TMDS input skew tolerance (1 full clock cycle), programmable DATACK phase alignment, HDCP key storage architecture, and 100-lead LQFP package compatibility with high-density video PCB layouts.

Technical Context

The AD9397KSTZ-150 implements a fully integrated DVI 1.0 receiver with three TMDS data channel pairs (Rx0±, Rx1±, Rx2±) and one TMDS clock pair (RxC±), all internally terminated to 50 Ω via RTERM-controlled 500 Ω resistor. Its HDCP 1.1 engine authenticates receivers, decrypts encrypted streams, and supports key renewability during active transmission using external EEPROM interfacing via MDA/MCL and DDCSDA/DDCSCL I²C buses.

It features a programmable color space converter (CSC) supporting RGB ↔ YCbCr bidirectional conversion at up to 150 MHz, configurable output formats (RGB 24-bit, YCbCr 4:4:4 or 4:2:2), and pixel sampling phase adjustment across 32 steps (0–360°) for optimal eye diagram alignment. Output timing maintains fixed relationships among DATACK, HSOUT, VSOUT, and DE through synchronous PLL-derived clocks.

FAQ

What is the maximum supported pixel clock frequency for the AD9397KSTZ-150?

The AD9397KSTZ-150 supports a maximum pixel clock frequency of 150 MHz, enabling full support for 1080p60, 720p60, and SXGA (1280×1024@80 Hz) display resolutions. This rating is confirmed in Table 1 and Table 2 of the Rev. 0 datasheet under AC specifications for AD9397KSTZ-150, with DATACK frequency (FCIP) specified as 20–150 MHz.

Does the AD9397KSTZ-150 include built-in HDCP functionality?

Yes, the AD9397KSTZ-150 integrates a complete HDCP 1.1 engine with internal key storage architecture. It performs receiver authentication, encrypted data decryption, and key renewability during active transmission, as documented in the General Description and HDCP section of the datasheet. External EEPROM interfacing via MCL/MDA is required for key provisioning.

Can the AD9397KSTZ-150 convert RGB input to YCbCr output?

Yes, the AD9397KSTZ-150 features a fully programmable color space converter (CSC) that supports bidirectional RGB ↔ YCbCr conversion. It accepts RGB input and outputs YCbCr in 4:4:4 or 4:2:2 formats at up to 150 MHz, with 13-bit coefficient resolution and dedicated filter for 4:4:4 → 4:2:2 downconversion, as detailed in the Color Space Conversion section.

What package type and lead count does the AD9397KSTZ-150 use?

The AD9397KSTZ-150 uses a 100-lead, Pb-free LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This is explicitly stated in the Features list and confirmed in the Outline Dimensions section (Page 28) and Pin Configuration diagram (Figure 2) of the Rev. 0 datasheet.

How is power managed on the AD9397KSTZ-150?

The AD9397KSTZ-150 implements four power states - full-power, seek mode, auto power-down, and power-down - controlled via serial register 0x26 and PWRDN pin. Power-down dissipation is 130 mW, and supply sequencing must ensure VD and VDD remain within ±300 mV of DVDD, as defined in the Power Management and Power Supply sections (Pages 10–11).
