Texas Instruments TLV3607RTER

Overview

TLV3607RTER from Texas Instruments is a dual-channel, 800ps propagation delay, rail-to-rail input comparator with LVDS outputs, operating from 2.4V to 5.5V supply. It delivers ±350mV differential output swing, 350ps overdrive dispersion, and 600ps minimum detectable pulse width-enabling precise time-of-flight measurement in LIDAR front-ends.

For engineers reviewing the TLV3607RTER datasheet, TLV3607RTER pinout, TLV3607RTER application, or TLV3607RTER equivalent, key selection criteria include channel count, LVDS interface compatibility, dual independent shutdown (SHDNA/SHDNB), adjustable hysteresis per channel, and WQFN-16 thermal performance for high-density optical sensor modules.

Technical Context

The TLV3607RTER implements a fully differential, rail-to-rail input stage extending 200mV beyond both VEE and VCCI rails, enabling zero-crossing detection without level-shifting. Its LVDS output stage drives standard 100Ω terminations directly, delivering 2.6Gbps toggle rate with suppressed common-mode noise.

Each channel features independent latch enable/hysteresis control (LE/HYSA/B) and active-low shutdown (SHDNA/SHDNB), supporting asynchronous channel gating and noise-immune latching in time-critical trigger paths-critical for oscilloscope sampling and drone vision synchronization.

FAQ

What is the maximum toggle rate supported by the TLV3607RTER?

The TLV3607RTER supports a maximum toggle rate of 2.6Gbps under typical conditions (VIN = 200mVPP sine wave, 50% output swing). This rating is validated across the full operating temperature range (–40°C to +125°C) and confirms its suitability for high-speed serial data path applications such as LIDAR echo decoding and FPGA clock domain crossing. The TLV3607RTER achieves this while maintaining LVDS compliance and low jitter.

Does the TLV3607RTER require external hysteresis for stable operation?

The TLV3607RTER includes an adjustable hysteresis function per channel via the LE/HYSA and LE/HYSB pins. With no external resistor, hysteresis is 0mV; connecting resistors (e.g., 56kΩ) yields up to 60mV hysteresis. External hysteresis is optional but recommended for noisy environments like photodiode front-ends. The TLV3607RTER does not require external feedback networks for basic comparator operation due to its internal architecture.

Can the TLV3607RTER operate with separate input and output supply voltages?

Yes-the TLV3607RTER features independent VCCI (input supply) and VCCO (output supply) pins, each supporting 2.4V to 5.5V. This allows level translation between domains-for example, a 3.3V input stage driving a 2.5V LVDS bus. Both supplies must share a common ground (VEE), and proper decoupling is required on each supply rail to maintain 800ps timing accuracy and noise immunity.

What is the thermal performance of the TLV3607RTER in its WQFN-16 package?

The TLV3607RTER in the RTE (WQFN-16) package has a junction-to-ambient thermal resistance (RθJA) of 72.1°C/W and junction-to-board (RθJB) of 45.9°C/W. Its exposed thermal pad must be soldered to a PCB copper pour for optimal heat dissipation. At full load (12.7mA per channel), junction temperature rise remains within safe limits up to +105°C ambient-validated for continuous operation in enclosed LIDAR modules.

How does the TLV3607RTER handle input signals beyond the supply rails?

The TLV3607RTER supports rail-to-rail inputs extending 200mV beyond both VEE and VCCI rails (e.g., down to VEE – 0.2V and up to VCCI + 0.2V). This eliminates need for external clamping or level-shifting in applications like transimpedance amplifier outputs. Input protection diodes clamp currents to ±10mA beyond these limits, preserving functionality without damage under transient overvoltage conditions.
