Diodes Incorporated PI6C49CB01Q2WEX

Overview

PI6C49CB01Q2WEX from Diodes Incorporated is a 1-to-1 differential-to-LVCMOS/LVTTL clock buffer translator with AEC-Q100 Grade 2 qualification (-40°C to 105°C), 360 MHz maximum output frequency, 500 ps part-to-part skew, and support for LVPECL/LVDS/LVHSTL/SSTL/HCSL differential inputs. It serves as a high-precision timing interface in automotive ADAS sensor synchronization and infotainment SoC clock distribution.

For engineers reviewing the PI6C49CB01Q2WEX datasheet, PI6C49CB01Q2WEX pinout, PI6C49CB01Q2WEX application, or PI6C49CB01Q2WEX equivalent, key selection criteria include additive phase jitter (0.09 ps RMS at 3.3 V), dual supply compatibility (2.5 V / 3.3 V), automotive temperature grading, and SOIC-W package footprint constraints.

Technical Context

This device implements a single-ended LVCMOS/LVTTL output stage driven by a flexible differential input pair (CLK/nCLK) with internal 51 kΩ pullup/pulldown resistors. It operates across two supply rails (2.5 V or 3.3 V) and maintains tight timing integrity via low propagation delay (1.6–2.5 ns) and sub-0.15 ps RMS additive jitter over 12 kHz–20 MHz integration bandwidth.

The architecture supports both true differential and single-ended input configurations using external bias networks. Its AEC-Q100 qualification, IATF16949 manufacturing, and PPAP capability confirm suitability for automotive safety-critical timing paths where deterministic skew (<500 ps) and thermal robustness (θJA = 103°C/W) are mandatory.

FAQ

What is the maximum input voltage tolerance for CLK and nCLK pins?

The absolute maximum input voltage for CLK and nCLK is –0.5 V to VDD + 0.5 V. For single-ended operation, the maximum input voltage is further limited to VDD + 0.3 V. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of DS42271 Rev 1-2.

Can PI6C49CB01Q2WEX operate with a 2.5 V supply while driving a 3.3 V load?

No. The output voltage swing is rail-to-rail relative to VDD; at 2.5 V supply, VOH is guaranteed ≥1.8 V and VOL ≤0.5 V into 50 Ω to VDD/2. Driving a 3.3 V logic domain requires VDD = 3.3 V. Level-shifting must be handled externally if interfacing mismatched voltage domains.

Is external biasing required when using LVDS input signals?

No. The internal 51 kΩ pullup on nCLK and pulldown on CLK provide sufficient termination for standard LVDS (100 Ω differential) inputs. External biasing is only needed for single-ended sources, where a VDD/2 reference must be applied to one input pin per Figure 1 in the datasheet.

Does PI6C49CB01Q2WEX support spread-spectrum clocking (SSC) inputs?

No. The device does not specify SSC tolerance in its AC characteristics or application notes. Its jitter specifications (e.g., 0.09 ps RMS) assume deterministic input waveforms. Introducing SSC may degrade output jitter performance beyond guaranteed limits and is not validated for automotive use cases.
