PI90LVB051L

Drivers, Receivers, Transceivers Overview

The PI90LVB051 is a differential line driver and receiver (transceiver) designed for high-speed data transmission. It operates on a single 3.3V power supply and supports signaling rates exceeding 660 Mbps. The device translates low-voltage TTL/CMOS inputs into LVDS differential outputs with a typical swing of ±350mV into a 50-ohm load, while the receiver converts differential signals back to 3V CMOS levels. Driver propagation delay is typically 1.5ns. The driver section features independent enable control via an active HIGH DEN pin, entering a high-impedance state when disabled. The receiver is controlled by an active LOW REN* pin. Input pins are 5V tolerant.

Drivers, Receivers, Transceivers Feature Summary

• Supports signaling rates greater than 660 Mbps using low-voltage differential signaling.
• Enables true half-duplex operation with doubled driver output current compared to standard LVDS.
• Features independently controllable driver and receiver sections with dedicated enable pins.
• Driver inputs are low-voltage TTL compatible and 5V tolerant.

Drivers, Receivers, Transceivers Applications

• Point-to-point and multidrop baseband data transmission over controlled impedance media.
• Intra-system connections via printed circuit board traces or cables.
• Hubs and routers for data communications.
• PBXs, switches, repeaters, and base stations for telecommunications.

Drivers, Receivers, Transceivers Procurement Notes

This component is obsolete as of March 22, 2006. The last purchase date was August 17, 2006, and the last shipment date was November 17, 2006. Verify availability through secondary market channels or consider replacement strategies due to end-of-life status.

Drivers, Receivers, Transceivers Selection Notes

Select this part for legacy designs requiring 3.3V LVDS transceivers with 5V-tolerant inputs. Ensure compatibility with 50-ohm differential transmission lines. Note that the device is discontinued; verify if existing inventory meets project requirements or if a modern equivalent is necessary for new production.

Drivers, Receivers, Transceivers Part Context

The PI90LVB051 belongs to the PI90LVB series from Pericom Semiconductor Corporation, which also includes the PI90LVB179, PI90LVB180, and PI90LVB050. These devices share similar LVDS functionality but differ in pin counts and package options. The PI90LVB051 specifically utilizes 16-pin TSSOP or SOIC packages.
