THCV235-Q-B

Overview

The THCV235-Q-B is a serializing IC designed to convert high-speed LVCMOS parallel signals into CML serial outputs for long-distance transmission. It supports up to 32-bit per pixel parallel input with operating voltages ranging from 1.7V to 3.6V. The device features dual CML serial output channels capable of data rates up to 4.0Gbps, with an actual operational rate of 3.2Gbps, enabling the transmission of 1080p60Hz 16-bit camera images over twisted pair or coaxial cables. It includes a bidirectional Sub-Link channel for I2C, UART, or GPIO signals. The component operates within a temperature range of -40°C to 105°C and utilizes a QFN64 package.

Feature Summary

• Converts LVCMOS parallel video signals to high-speed CML serial data for extended cable transmission
• Integrates a dedicated bidirectional Sub-Link channel for auxiliary control signals such as I2C and GPIO
• Supports RGB to YCbCr color space conversion for bandwidth compression in automotive applications

Applications

• Automotive imaging systems requiring robust signal transmission
• Surveillance cameras utilizing twisted pair or coaxial cabling
• Industrial vision equipment needing high-bandwidth video transfer

Procurement Notes

Verify that the specific suffix '-Q-B' corresponds to the qualified automotive grade variant as defined by the manufacturer's official documentation. Confirm package integrity and pinout compatibility with the QFN64 footprint during sourcing. Ensure supply chain sources provide traceability for automotive qualification standards required for this model.

Selection Notes

Select this component when converting parallel camera interfaces to serial links for distances exceeding standard PCB traces. It is suitable for designs requiring integrated color space conversion and auxiliary control channels. Verify that the host system supports the required 1.7V to 3.6V power domain and that the downstream receiver matches the CML output specifications.

Part Context

This part belongs to the THine Solutions THCV series of video serializers. It is specifically engineered for automotive and industrial environments where signal integrity over long cables is critical. The device complements receivers like the THCV236 to form complete transmission solutions for high-resolution video feeds in constrained spaces.

Replacement Considerations

Publicly confirmed substitutes include the THCV236-Q when used as the corresponding receiver unit in a paired configuration. Direct single-chip replacements are not documented; system redesign may be necessary if migrating to different serializer architectures.
