Renesas 83021AMILFT

Overview

83021AMILFT from IDT is a 1-to-1 differential-to-LVCMOS/LVTTL clock translator with differential CLK/nCLK inputs supporting LVPECL, LVDS, LVHSTL, SSTL, and HCSL signal types, 350MHz max output frequency, 500ps max part-to-part skew, and dual 3.3V/2.5V supply operation for timing interface bridging in high-speed digital systems.

For engineers reviewing the 83021AMILFT datasheet, 83021AMILFT pinout, 83021AMILFT application, or 83021AMILFT equivalent, this device serves as a low-jitter (0.21ps RMS additive phase jitter), space-efficient (8-lead SOIC) clock level shifter critical for FPGA-to-ASIC clock domain interfacing, memory controller timing synchronization, and multi-voltage SoC clock distribution.

Technical Context

The 83021AMILFT implements a single-ended LVCMOS/LVTTL output stage driven by a fully differential input comparator with internal 51kΩ pullup on nCLK and pulldown on CLK, enabling robust acceptance of five industry-standard differential signaling families without external biasing in many configurations.

Its AC performance is characterized at both 3.3V and 2.5V VDD, with propagation delay tightly specified (1.7–2.5ns), output duty cycle maintained across frequency bands (40–60% up to 350MHz), and rise/fall times controlled (100–550ps) to minimize EMI and ensure clean edge integrity in dense PCB layouts.

Key Specifications

FAQ

What is the maximum operating frequency of the 83021AMILFT?

The 83021AMILFT supports a maximum output frequency of 350MHz, verified under both 3.3V and 2.5V supply conditions across the full −40°C to +85°C operating temperature range. This specification applies to the Q0 LVCMOS/LVTTL output when driven by any supported differential input type (LVPECL, LVDS, LVHSTL, SSTL, or HCSL), and is measured with standard load conditions per the datasheet test setup.

Does the 83021AMILFT support both 2.5V and 3.3V supply voltages simultaneously?

No-the 83021AMILFT operates from a single VDD supply that may be either 2.5V (2.375V–2.625V) or 3.3V (3.0V–3.6V), but not both simultaneously. The device automatically adapts its input thresholds and output drive strength to the selected VDD level, enabling flexible deployment in mixed-voltage systems without external level-shifting components.

What differential input standards does the 83021AMILFT accept?

The 83021AMILFT accepts LVPECL, LVDS, LVHSTL, SSTL, and HCSL differential input signals on its CLK/nCLK pair. This broad compatibility is enabled by internal 51kΩ pullup on nCLK and pulldown on CLK, allowing proper common-mode biasing across all five standards without external resistors in most configurations, as confirmed in the datasheet's Application Information section.

Is the 83021AMILFT pin-compatible with any other clock translator devices?

Yes-the 83021AMILFT is pin-to-pin compatible with the MC100EPT21, sharing identical 8-lead SOIC (M) package pinout, CLK/nCLK input assignment, Q0 output location, and VDD/GND positions. This allows drop-in replacement in existing designs using the MC100EPT21, provided the 2.5V supply capability of the 83021AMILFT is not required.

What is the additive phase jitter performance of the 83021AMILFT?

The 83021AMILFT delivers 0.21ps RMS additive phase jitter (typical) at a 100MHz carrier frequency with integration limits from 637kHz to 10MHz, measured with 3.3V output. This value reflects jitter contributed solely by the device-not the input source-and is critical for maintaining timing margins in high-speed serial links, ADC sampling clocks, and RF data converters where spectral purity directly impacts system BER or ENOB.
