Product details

Overview

83021AMILF from Renesas Electronics (formerly 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, 350 MHz output frequency, 500 ps max part-to-part skew, and dual 3.3 V / 2.5 V supply operation for timing interface bridging in high-speed digital systems.

For engineers reviewing the 83021AMILF datasheet, 83021AMILF pinout, 83021AMILF application, or 83021AMILF equivalent, this device serves as a low-jitter, multi-standard clock level shifter in FPGA-to-ASIC interconnects, DDR memory clocking, and telecom line-card timing synchronization where board space and signal integrity are critical.

Technical Context

The 83021AMILF implements a single-ended LVCMOS/LVTTL output stage driven by a fully differential input comparator with internal 51 kΩ pullup on nCLK and pulldown on CLK, enabling robust acceptance of five industry-standard differential logic families without external biasing. Its propagation delay is tightly controlled at 1.7–2.5 ns across voltage and temperature.

It delivers 0.21 ps RMS additive phase jitter (100 MHz carrier, 637 kHz–10 MHz integration), supports 40–60% output duty cycle over full frequency range, and maintains stable timing performance under -40°C to +85°C ambient conditions with 3.3 V or 2.5 V supply rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequency	350 MHz maximum - enables direct clocking of high-speed SerDes, DDR3/4 PHYs, and FPGA I/O banks.
Additive Phase Jitter (RMS)	0.21 ps typical (100 MHz, 637 kHz–10 MHz) - ensures low BER in serial link receivers and jitter-sensitive PLLs.
Part-to-Part Skew	500 ps maximum - guarantees deterministic timing alignment across multiple devices in parallel clock distribution networks.
Supply Voltage Range	2.375–2.625 V or 3.0–3.6 V - allows seamless integration into mixed-voltage systems with 2.5 V or 3.3 V core/logic domains.
Input Compatibility	LVPECL, LVDS, LVHSTL, SSTL, HCSL - eliminates need for discrete level-shifting components when interfacing diverse clock sources.
Operating Temperature	-40°C to +85°C - qualified for industrial and telecom infrastructure applications without derating.

Pinout & Package

83021AMILF is housed in an 8-lead SOIC (M package), 3.9 mm × 4.9 mm × 1.375 mm body, lead-free, with standard 150-mil width and JEDEC MS-012 compliant footprint.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 6	nc	No-connect terminals - must remain unconnected per design; no internal function or parasitic loading impact.
2	CLK	Non-inverting differential input with internal 51 kΩ pulldown - accepts AC-coupled or DC-coupled differential signals with defined common-mode range.
3	nCLK	Inverting differential input with internal 51 kΩ pullup - forms matched pair with CLK for noise-rejecting clock reception.
5	GND	Power supply ground reference - requires low-inductance connection to system ground plane for jitter minimization.
7	Q0	LVCMOS/LVTTL single-ended clock output - drives 50 Ω terminated loads at VDD/2 with 100–400 ps rise/fall times.
8	VDD	Positive supply pin - supplies both input receiver and output driver; bypass capacitor required per datasheet layout guidelines.

Key Features

Feature	Design Value
Multi-standard differential input acceptance	Single device replaces five discrete translators - reduces BOM count and PCB area in mixed-signal timing paths.
Internal input termination resistors	51 kΩ pullup on nCLK and pulldown on CLK - eliminates external bias network for most LVDS/LVPECL sources, simplifying layout.
Low additive phase jitter	0.21 ps RMS (typical) - preserves signal integrity for 10 GbE, CPRI, and PCIe Gen3+ clock recovery circuits.
Dual-supply compatibility	Operates at either 2.5 V or 3.3 V - enables drop-in use in legacy 3.3 V systems and modern low-voltage ASIC/FPGA designs.
Small-footprint SOIC package	8-lead, 150-mil SOIC - fits tight spacing constraints in dense telecom line cards and compact embedded modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar clock translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC100EPT21DG	Pin-to-pin compatible, same SOIC-8 package, but requires external VBB bias for LVPECL input; no internal pullup/pulldown resistors.	Higher layout complexity due to external bias network; not suitable for LVDS-only systems without redesign.	Select when legacy MC100EPT21 footprint reuse is mandatory and LVPECL biasing infrastructure already exists.
Si53301-B-GM	Programmable 1:1 clock buffer with integrated PLL; larger QFN-24 package; supports wider input voltage range and spread-spectrum rejection.	Over-engineered for simple level translation; adds unnecessary cost and configuration overhead in fixed-frequency applications.	Select only if dynamic frequency adjustment, jitter cleaning, or multi-output fanout beyond Q0 is required.

Compared with MC100EPT21DG and Si53301-B-GM, the 83021AMILF offers optimal balance of simplicity, low jitter, and multi-standard input support in minimal SOIC-8 footprint - ideal for cost-sensitive, space-constrained, fixed-frequency clock bridging where external biasing must be avoided.

FAQ

What input signal standards does the 83021AMILF support?

The 83021AMILF supports LVPECL, LVDS, LVHSTL, SSTL, and HCSL differential input standards via its CLK/nCLK pair. It accepts these signals without external biasing due to internal 51 kΩ pullup on nCLK and pulldown on CLK. The 83021AMILF datasheet confirms compatibility across all five standards under specified VPP and VCMR ranges, making it suitable for heterogeneous clock source environments.

Does the 83021AMILF require external termination resistors?

No, the 83021AMILF does not require external termination resistors for standard LVDS or LVPECL inputs because it integrates internal 51 kΩ pullup on nCLK and pulldown on CLK. However, external series or parallel termination may still be needed depending on source impedance and trace length - refer to Figures 2A–2F in the 83021AMILF datasheet for vendor-specific interface examples.

What is the maximum guaranteed output frequency of the 83021AMILF?

The 83021AMILF guarantees 350 MHz maximum output frequency across its full operating range (-40°C to +85°C, 2.5 V or 3.3 V supply). This value is specified in Tables 4A and 4B of the 83021AMILF datasheet under AC Electrical Characteristics and applies to both supply voltages with measured tPD and odc compliance.

How does the 83021AMILF handle power supply selection between 2.5 V and 3.3 V?

The 83021AMILF operates natively at either 2.5 V (2.375–2.625 V) or 3.3 V (3.0–3.6 V) without configuration - VDD voltage automatically sets output logic levels and input threshold references. DC and AC parameters, including VOH/VOL and fMAX, are separately characterized for each rail in the 83021AMILF datasheet, ensuring reliable operation in mixed-voltage systems.

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

Yes, the 83021AMILF is pin-to-pin compatible with the MC100EPT21, as confirmed in the Reliability Information section (Page 9) of the 83021AMILF datasheet. Both use identical 8-lead SOIC (M) package and share matching pin assignments for VDD, GND, CLK, nCLK, Q0, and nc terminals - enabling direct replacement where internal biasing requirements align.
