Overview
The BU7988KVT is an LVDS serializer manufactured by ROHM Semiconductor, designed to convert parallel data into a serial stream. It accepts 56-bit parallel inputs and outputs 8 LVDS channels. The device operates on a supply voltage ranging from 3V to 3.6V, with a typical value of 3.3V. It supports clock frequencies between 8MHz and 112MHz, achieving maximum data rates of 784Mbps. The component functions within an operating temperature range of -20°C to 85°C and is housed in a 100-TQFP package measuring 14x14mm.
Feature Summary
- Supports spread spectrum clocking for EMI reduction
- Features selectable low swing mode for lower electromagnetic interference
- Includes power down mode for energy efficiency
- Allows selection of latch boundaries for flexible configuration
Applications
- High-speed digital signal transmission systems
- Video interface circuits requiring LVDS serialization
- Industrial equipment with high noise immunity requirements
Procurement Notes
Verify the current supply status as this component may be discontinued or subject to last-time buy notifications. Confirm RoHS compliance and lead times through official distributors. Ensure the specific ordering suffix matches the required packaging format before procurement.
Selection Notes
Select this component when a 56-to-8 LVDS serializer is required for high-speed data conversion. Verify that the system operates within the specified 3V to 3.6V voltage range and -20°C to 85°C temperature limits. Consider the 100-TQFP package constraints during PCB layout design.
Part Context
This part belongs to the BU7988 series of LVDS SerDes devices from ROHM Semiconductor. It is specifically engineered for applications needing reliable high-speed serial transmission over differential pairs. The series focuses on reducing electromagnetic interference through features like spread spectrum and low swing modes.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family. Verify if newer revisions offer improved availability while maintaining identical electrical characteristics and package dimensions.
