ISL34340INZ-T13

Serializers, Deserializers Overview

The ISL34340INZ-T13 is a serializer/deserializer for LVCMOS parallel video data, packaged in a 64-lead EPTQFP with tape and reel configuration. It transports 24-bit RGB video over a single differential pair using 8b/10b encoding at up to 40MHz PCLK. The device supports bidirectional auxiliary data transfer during vertical retrace intervals without extra bandwidth. Operating temperatures range from -40°C to +85°C. Power supplies include 1.8V for core/clock recovery and 3.3V for I/O, analog, and PLL sections.

Serializers, Deserializers Feature Summary

• Bidirectional side-channel transport of auxiliary data over the same differential link used for video
• Internal 100Ω termination on high-speed serial lines with DC balanced 8b/10b line coding
• Transmitter amplitude boost, pre-emphasis, and receiver equalization for extended cable reach
• Configurable as either serializer or deserializer via a single control pin

Serializers, Deserializers Applications

• Navigation and display systems
• Video entertainment systems
• Industrial computing terminals
• Remote cameras

Serializers, Deserializers Procurement Notes

Verify the T13 suffix indicates tape and reel packaging per TB347 specifications. Confirm RoHS compliance and Pb-free status through manufacturer documentation. Ensure the ordering part number matches the specific package variant required for your assembly process.

Serializers, Deserializers Selection Notes

This component functions identically as both serializer and deserializer based on the VIDEO_TX pin state, simplifying inventory management. Designers must ensure proper power sequencing where the 3.3V supply precedes the 1.8V supply. AC-coupling capacitors are strictly specified at 27nF for the SERIO pins to maintain signal integrity.

Serializers, Deserializers Part Context

Manufactured by Renesas Electronics Corporation (formerly Intersil), this device belongs to the WS-VGA long-range video SERDES family. It is designed for applications requiring robust video transmission over single differential pairs while maintaining low electromagnetic interference and simplified cabling architectures.

Serializers, Deserializers Replacement Considerations

The datasheet explicitly recommends the ISL34341 as the replacement part for new designs. Verify compatibility regarding pinout and electrical characteristics before substitution.

Serializers, Deserializers FAQ

How is the device configured as a serializer or deserializer?

The role is determined by the logic level on the VIDEO_TX pin. A high level configures the device as a serializer, while a low level configures it as a deserializer.

What is the purpose of the REF_RES pin?

The REF_RES pin connects to an analog bias setting resistor. A 3.16kΩ ±1% resistor to ground is required for proper operation.

Why are multiple ground pins provided?

Different ground pins (GND_P, GND_IO, GND_CDR, etc.) assist in minimizing current loops during bypassing. They are internally weakly connected but should be tied together externally to emulate a common ground plane.
