LTC1520CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1520CS#PBF is a precision quad line receiver manufactured by Analog Devices Inc. It operates from a single 5V supply and supports data rates up to 50Mbps. The device features a propagation delay of 18ns with a tolerance of ±3ns over the operating temperature range. Key electrical parameters include a typical high-to-low and low-to-high skew (tPLH/tPHL) of 500ps and a channel-to-channel skew of 400ps. The input resistance is guaranteed to be at least 18kΩ, even when unpowered. The component is housed in a 16-lead narrow SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delays and minimal skew across wide input common mode ranges and temperature variations.
• Hot-swap capability provided by high input resistance that persists when the device is unpowered or disabled.
• Integrated protection mechanisms include thermal shutdown and short-circuit current limiting to prevent latchup damage.

Drivers, Receivers, Transceivers Applications

• High speed backplane interface
• PECL and LVDS line receivers
• Tapped delay line
• Ring oscillator

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the CS variant meets the required commercial operating temperature range of 0°C to 70°C. Ensure the 16-lead narrow SO package dimensions align with the target PCB footprint constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring tight propagation delay matching and low skew between channels. It is suitable for translating differential signals to CMOS/TTL levels. Consider the 12mA supply current and 5V single-supply requirement during power budgeting. Verify compatibility with driver output swings and transmission line characteristics.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1520 series of high-speed precision line receivers. It is designed for parallel data transmission where timing accuracy is critical. The device complements other interface solutions by offering rail-to-rail input common mode range and hot-swap safety without external components.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the LTC1518 and LTC1519. These parts also offer 50Mbps operation but feature an extended common mode range of –7V to 12V. Verify pinout compatibility and electrical parameter alignment before substitution.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the LTC1520?

The LTC1520 supports data rates as high as 50Mbps.

How does the device behave when unpowered?

When unpowered or disabled, the receiver inputs maintain a high resistance of at least 18kΩ, allowing the device to be hot-swapped without loading the data lines.

What is the typical channel-to-channel skew?

The typical channel-to-channel skew is 400ps under standard test conditions.
