GTL2006PW,112

Translators, Level Shifters Overview

The GTL2006PW,112 is a 13-bit translator designed to interface between 3.3 V LVTTL chipsets and Xeon processor GTL-/GTL/GTL+ I/Os. It operates as a GTL- to LVTTL sampling receiver or an LVTTL to GTL- driver within a 3.0 V to 3.6 V supply range. The device features series termination on the LVTTL outputs of 30 Ω. It provides ESD protection exceeding 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 250 V CDM per JESD22-C101.

• LVTTL to GTL- driver implementations

Translators, Level Shifters Procurement Notes

Verify that the specific ordering code matches the required package and temperature range. Confirm that the system design accommodates the non-5V tolerant nature of the LVTTL I/O pins. Ensure proper handling procedures are followed due to the high ESD sensitivity ratings specified in the datasheet. Cross-reference the pin configuration with the target PCB layout to ensure compatibility with the TSSOP28 package dimensions.

Translators, Level Shifters Selection Notes

Select this component when interfacing 3.3 V LVTTL logic with Xeon processor GTL- signaling standards. It is suitable for platform health management tasks requiring bidirectional translation. Consider the 30 Ω output termination for impedance matching. Verify that the operating voltage range of 3.0 V to 3.6 V aligns with the system power rails. Note that the LVTTL inputs are not 5 V tolerant, which restricts direct connection to 5 V logic without level shifting.

Translators, Level Shifters Part Context

This device belongs to the GTL200x family of translators manufactured by Philips Semiconductors, now NXP. It is specifically engineered for server and workstation architectures utilizing Intel Xeon processors. The component facilitates reliable data transfer between different logic families commonly found in high-performance computing platforms. It serves as a critical interface element in complex digital systems requiring mixed-voltage operation.

Translators, Level Shifters Replacement Considerations

Check for updated part numbers from NXP Semiconductors if Philips branding is no longer supported. Verify functional equivalence regarding pinout and electrical characteristics before substitution. Ensure any replacement maintains the same 13-bit translation capability and GTL/LVTTL compatibility.

Translators, Level Shifters FAQ

Are the LVTTL inputs high impedance when the device is unpowered?

Yes, when the device is unpowered, the LVTTL inputs remain in a high-impedance state and will not leak to the VDD rail even if pulled high.

Can the GTL2006 operate with VTT at 1.2 V and VREF at 0.6 V?

Yes, the device can operate with VTT up to 3.6 V and VREF between 0.5 V and 1.8 V at any VTT, allowing adjustment of noise margins independent of standard GTL specifications.

What causes the slow transition time in the Bn to Bn timing specification?

The slow enable time is deliberate to prevent glitches or false LOWs on the 7BOn outputs, accounting for potentially slow rise times on the open-drain I/Os connected to 5A and 6A.
