Texas Instruments DS90CF366MTD/NOPB

Overview

DS90CF366MTD/NOPB from Texas Instruments is a 3.3-V LVDS receiver that converts three LVDS data streams and one LVDS clock into 21-bit parallel LVCMOS output (18-bit RGB + HSYNC/VSYNC/DE), supporting 20–85 MHz shift clock rates with 595 Mbps per LVDS lane and 1.785 Gbps aggregate throughput. It features an internal PLL, 48-pin TSSOP package, and power-down mode consuming ≤400 µA.

For engineers reviewing the DS90CF366MTD/NOPB datasheet, DS90CF366MTD/NOPB pinout, DS90CF366MTD/NOPB application, or DS90CF366MTD/NOPB equivalent, key selection criteria include LVDS-to-LVCMOS deserialization for flat-panel display interfaces, 85 MHz maximum clock rate, 21-bit output mapping, and compatibility with FPD-Link I transmitters in embedded video systems.

Technical Context

The DS90CF366MTD/NOPB implements a phase-locked loop (PLL) to recover the incoming LVDS clock (20–85 MHz), enabling precise sampling of three serialized LVDS data lanes at 7 bits per clock cycle. Its deserialization architecture maps each LVDS lane to seven LVCMOS outputs, yielding 21 total outputs strobed on the falling edge of RxCLKOUT.

It requires external 100-Ω differential termination on each LVDS input pair and supports power-down via active-low PWR_DWN, reducing supply current to ≤400 µA while holding outputs low. The device operates from 3.0–3.6 V and is rated for –10°C to +70°C ambient temperature.

Key Specifications

Pinout & Package

DS90CF366MTD/NOPB uses a 48-pin TSSOP (DGG) package measuring 12.50 mm × 6.10 mm, with dedicated LVDS input, PLL, and LVCMOS output power/ground domains.

FAQ

What is the maximum supported pixel clock frequency for DS90CF366MTD/NOPB?

The DS90CF366MTD/NOPB supports a maximum shift clock frequency of 85 MHz, enabling single-pixel timing for resolutions up to SXGA (1280×1024) at 60 Hz. This is confirmed in the datasheet's Recommended Operating Conditions and Switching Characteristics sections, where RSPos timing parameters and RCOP period are specified at 85 MHz operation. The device maintains valid setup/hold margins and skew tolerance up to this rate.

Does DS90CF366MTD/NOPB require external components for PLL operation?

No, DS90CF366MTD/NOPB does not require external components for PLL operation. As stated in the Features section and Detailed Description, the internal PLL "requires no external components" and locks directly to the incoming LVDS clock (20–85 MHz). External bypassing (e.g., 0.1 µF ceramic capacitors per VCC pin) is required for noise suppression but not for PLL functionality.

How is the 21-bit output mapped on DS90CF366MTD/NOPB?

The DS90CF366MTD/NOPB outputs 21 LVCMOS signals: RxOUT0–RxOUT17 carry 18-bit RGB (6 bits per color channel), while RxOUT18, RxOUT19, and RxOUT20 carry HSYNC, VSYNC, and DE (Data Enable), respectively. This mapping is explicitly defined in Figure 9 ("DS90CF366 Mapping") and Pin Functions table of the datasheet, and is fixed-not configurable via registers or pins.

What is the power consumption of DS90CF366MTD/NOPB at 85 MHz?

At 85 MHz with worst-case pattern loading, DS90CF366MTD/NOPB draws 90–115 mA (typical to maximum) from VCC, corresponding to ~300–380 mW. In 16-grayscale mode (representative of typical LCD usage), current drops to 43–70 mA. Power-down mode reduces current to ≤400 µA. All values are specified in Section 6.5 Electrical Characteristics under ICCRW and ICCRG conditions.

Can DS90CF366MTD/NOPB interface directly with a 24-bit RGB display?

No, DS90CF366MTD/NOPB cannot natively drive a 24-bit RGB display because it provides only 18-bit RGB output (6 bits per channel) plus 3 control signals. For 24-bit support, TI recommends DS90CF386MTD/NOPB, which delivers 24-bit RGB + 4 control signals. Using DS90CF366MTD/NOPB with a 24-bit display would require external bit expansion or dithering, compromising color fidelity and violating its specified output capability.
