Product details

Overview

GTL2007PW,112 from NXP Semiconductors is a 12-bit GTL-to-LVTTL bidirectional translator with dual enable-controlled power-good monitoring for Xeon processor platforms. It interfaces GTL signals (VTT = 1.1–1.2 V, Vref = 0.64–1.1 V) with LVTTL logic (3.0–3.6 V), features EN1/EN2 inputs to disable error outputs during unexpected power-down events, and supports critical platform health management functions in dual-CPU server motherboards.

For engineers reviewing the GTL2007PW,112 datasheet, GTL2007PW,112 pinout, GTL2007PW,112 application, or GTL2007PW,112 equivalent, this device is selected for high-reliability translation between CPU thermal trip (THRMTRIP_L), PROCHOT_L, IERR_L, and SMI/NMI signals across GTL and LVTTL domains in Intel Xeon-based server platforms requiring precise voltage-level isolation and glitch-free error reporting.

Technical Context

The GTL2007PW,112 implements two independent enable-controlled signal paths: EN1 gates 1AO/2AO and 5A (open-drain), while EN2 gates 3AO/4AO and 6A (open-drain), each with internal delay to suppress LOW glitches on 7BO1/7BO2 outputs during transient transitions. Its architecture supports simultaneous GTL input sampling (e.g., 1BI–4BI, 9BI, 11BI) and LVTTL output driving (e.g., 1AO–4AO, 9AO) with series-terminated 30 Ω LVTTL outputs.

It operates across −40 °C to +85 °C ambient temperature, accepts VCC = 3.0–3.6 V, and maintains stable DC/AC performance across Vref = 0.64–1.1 V - enabling compatibility with evolving VTT/Vref ratios down to 0.63×VTT (min 0.693 V at VTT = 1.1 V). Propagation delays range from 1 ns (tPLH, nA→nB) to 350 ns (tPHL, 5BI→7BO1) depending on signal path and load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	3.0 V to 3.6 V - ensures compatibility with standard 3.3 V LVTTL supply rails and margin against rail droop in server power delivery systems.
Vref Range	0.64 V to 1.1 V - supports GTL reference voltage scaling for future VTT reductions while maintaining valid logic thresholds (VIL ≤ Vref − 0.05 V, VIH ≥ Vref + 0.05 V).
Propagation Delay (tPLH/tPHL)	1–10 ns (LVTTL↔GTL data paths); up to 350 ns (PROCHOT_L error paths) - enables timing-critical CPU health signaling with controlled latency for fault isolation.
LVTTL Output Termination	30 Ω series resistance - provides impedance matching to reduce reflections on high-speed LVTTL traces without external resistors.
ESD Protection	2000 V HBM, 200 V MM, 1000 V CDM - meets industrial-grade robustness requirements for handling during server board assembly and field service.
Input/Output Capacitance	1.5–3.5 pF - minimizes loading on GTL and LVTTL buses, preserving signal integrity in dense multi-processor interconnects.
Operating Temperature	−40 °C to +85 °C - qualified for extended thermal environments in rack-mounted server chassis with active airflow constraints.

Pin/Terminal	Circuit Role	Design Meaning
VREF (1)	GTL reference voltage input	Sets GTL input threshold (VIH ≥ Vref + 0.05 V, VIL ≤ Vref − 0.05 V); supports 0.64–1.1 V for forward voltage scalability.
1AO–4AO, 9AO (2–4, 10–11, 15)	LVTTL output	Push-pull outputs with 30 Ω series termination; drive South Bridge/SMBus-compatible logic levels (VOH ≥ 2.1 V @ 16 mA, VOL ≤ 0.4 V @ 4 mA).

EN1/EN2 (6, 23)	LVTTL enable input	Active-HIGH control signals that disconnect 5BI/6BI from 7BO1/7BO2 outputs during power loss, preventing false error propagation to monitoring agents.
1BI–4BI, 9BI, 11BI (27, 26, 19–18, 9, 7)	GTL input	Accept GTL signals (VTT = 1.1–1.2 V); high-impedance inputs with <2.5 pF capacitance preserve bus timing in multi-drop configurations.
7BO1/7BO2, 10BO1/10BO2, 11BO (25, 24, 17, 16, 22)	GTL output	Drive GTL-compliant outputs (VOL ≤ 0.4 V @ 15 mA, VOH ≈ VTT); include internal delay to suppress glitches during enable transitions.
VCC (28), GND (14)	Power supply	Single 3.0–3.6 V supply; decoupling required near VCC/GND pins to maintain noise immunity in high-frequency GTL switching.

Key Features

Feature	Design Value
Dual enable-controlled error suppression	EN1 and EN2 independently gate PROCHOT_L and SMI-related outputs (7BO1/7BO2, 10BO1/10BO2) to prevent false alerts during CPU thermal trip or VRD power loss.

Scalable Vref operation	Valid down to 0.64 V reference voltage - accommodates future GTL voltage scaling (e.g., 0.63×VTT) without redesigning reference circuitry.
Integrated 30 Ω LVTTL output termination	Eliminates need for external series resistors on 1AO–4AO and 9AO outputs, reducing BOM count and PCB area in space-constrained server DIMM slots and CPU sockets.
Robust ESD and latch-up immunity	2000 V HBM ESD rating and >500 mA latch-up current compliance ensure reliability during automated board handling and field-level maintenance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar GTL-to-LVTTL translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
GTL2006PW,112	No EN1/EN2 enable inputs; fixed error output behavior without power-good gating.	Cannot suppress false error reports during unexpected power loss; requires external logic for enable control.	Select when system-level power sequencing is handled externally and minimal BOM cost is prioritized over fault-isolation capability.
SN74AVC16T245DGGR	3.3 V only; no GTL-specific Vref support; higher 5.5 V tolerance not needed in GTL systems.	Designed for general-purpose AVC translation, not optimized for Intel Xeon GTL voltage thresholds or PROCHOT_L timing requirements.	Select only for non-server LVTTL↔LVCMOS applications where GTL reference precision and enable-controlled error suppression are unnecessary.

Compared with GTL2007PW,112, the GTL2006PW,112 lacks integrated enable logic for error suppression, while the SN74AVC16T245DGGR omits GTL-specific Vref configuration and fails to meet the sub-10 ns propagation delay and 0.64 V minimum Vref requirements critical for Xeon platform health signaling.

FAQ

What is the primary function of the GTL2007PW,112 in a dual-Xeon server platform?

The GTL2007PW,112 serves as a 12-bit bidirectional GTL-to-LVTTL translator with dual enable inputs (EN1/EN2) to condition and gate error signals such as THRMTRIP_L, PROCHOT_L, and IERR_L between Xeon processors and platform health management logic. Its core function is to prevent false error reporting during unexpected power-down events by disabling GTL outputs (7BO1/7BO2) when EN1 or EN2 goes LOW - a capability essential for accurate diagnostics in enterprise server environments where GTL2007PW,112 is deployed.

How does the GTL2007PW,112 handle Vref voltage scaling for future GTL implementations?

The GTL2007PW,112 supports Vref from 0.64 V to 1.1 V, explicitly accommodating future GTL voltage scaling down to 0.63×VTT (e.g., 0.693 V at VTT = 1.1 V). Characterization confirms minimal DC/AC performance variation across this range, allowing designers to retain GTL2007PW,112 in next-generation platforms without requalification - provided Vref remains within the validated window and meets the VIH/VIL thresholds (±0.05 V around Vref) specified in the GTL2007PW,112 datasheet.

Can the GTL2007PW,112 be used without external pull-up resistors on its open-drain outputs?

No - the GTL2007PW,112's open-drain LVTTL I/O pins (5A, 6A) require external pull-up resistors (typically 1.2–1.5 kΩ to VCC) to establish HIGH-state logic levels, as specified in Intel's PROCHOT_L and FORCEPR_L interface guidelines. The GTL2007PW,112 itself does not provide internal pull-ups; omitting external resistors would result in undefined or floating states on these critical control lines, compromising system reliability and violating the GTL2007PW,112's functional operation per Table 5 and Table 6.

What is the significance of the 30 Ω series termination on GTL2007PW,112's LVTTL outputs?

The integrated 30 Ω series termination on GTL2007PW,112's LVTTL outputs (1AO–4AO, 9AO) matches typical PCB trace impedances in server motherboard layouts, minimizing signal reflections and overshoot on high-speed LVTTL buses. This eliminates the need for discrete 30 Ω resistors per output, reducing component count, PCB area, and potential solder joint failures - a key reliability enhancement for GTL2007PW,112 deployments in thermally stressed server environments where layout density and long-term stability are critical.

Does the GTL2007PW,112 support 5 V tolerant LVTTL I/O?

No - the GTL2007PW,112's LVTTL I/O is explicitly rated for 3.0–3.6 V operation only and is not 5 V tolerant. Applying 5 V to any LVTTL input (e.g., EN1, EN2, 1AO–4AO) exceeds the absolute maximum input voltage rating of +4.6 V and risks permanent damage. System designs must ensure all connected LVTTL logic operates strictly within the 3.0–3.6 V range, as defined in the GTL2007PW,112's recommended operating conditions and limiting values tables.
