Product details

Overview

830S21AMI-01LF 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 levels, a single LVCMOS/LVTTL output (Q), 350MHz max frequency, and operation from 2.5V or 3.3V supply. It serves as a high-fidelity clock interface in FPGA-to-ASIC timing paths requiring low skew and low additive jitter.

For engineers reviewing the 830S21AMI-01LF datasheet, 830S21AMI-01LF pinout, 830S21AMI-01LF application, or 830S21AMI-01LF equivalent, key selection criteria include input compatibility across five differential standards, sub-0.12ps RMS additive phase jitter at 350MHz, part-to-part skew ≤525ps, and SOIC-8 footprint suitability for space-constrained timing interfaces.

Technical Context

The 830S21AMI-01LF implements a single-ended buffer stage following a fully differential input comparator with internal 51kΩ pullup/pulldown resistors on CLK/nCLK. Its OE-controlled output driver supports 3.3V or 2.5V LVCMOS/LVTTL logic levels with 10–12Ω output impedance and guaranteed 47–53% duty cycle up to 266MHz.

It operates across –40°C to +85°C ambient, accepts common-mode input voltages from GND+0.5V to VDD–0.85V, and delivers 0.95–2.0ns propagation delay depending on supply voltage. Additive phase jitter is measured over 12kHz–20MHz integration bandwidth and specified at 0.11ps RMS for 350MHz output.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Output Frequency	350MHz - supports high-speed serial link reference clocks and DDR memory timing.
Additive Phase Jitter (RMS)	0.11ps typical (12kHz–20MHz) - enables low-BER operation in SerDes and RF sampling systems.
Part-to-Part Skew	525ps maximum - ensures deterministic timing alignment across multiple translator instances in parallel clock trees.
Supply Voltage Range	2.5V ±5% or 3.3V ±5% - interoperable with core logic domains without level-shifting circuitry.
Input Compatibility	LVPECL, LVDS, LVHSTL, SSTL, HCSL - eliminates need for external termination or bias networks in mixed-signal board designs.
Output Drive Strength	10Ω @ 3.3V / 12Ω @ 2.5V - matches standard 50Ω transmission lines when terminated to VDD/2.
Operating Temperature	–40°C to +85°C - qualified for industrial and telecom infrastructure environments.

Pinout & Package

830S21AMI-01LF is housed in an 8-lead SOIC package (M suffix), 3.9mm × 4.9mm × 1.375mm body, RoHS-compliant lead-free construction.

Pin/Terminal	Circuit Role	Design Meaning
1, 6	nc	No-connect terminals - must remain unconnected per datasheet; no internal function.
2	CLK	Non-inverting differential clock input with internal 51kΩ pullup/pulldown - accepts LVPECL/LVDS/LVHSTL/SSTL/HCSL signals.
3	nCLK	Inverting differential clock input with internal 51kΩ pullup/pulldown - forms differential pair with Pin 2 for noise-immune clock reception.
4	OE	Active-high output enable - drives Q into high-impedance state when low; default-enabled at power-up.
5	GND	Power supply ground reference - requires low-inductance connection to system ground plane.
7	Q	LVCMOS/LVTTL single-ended clock output - rail-to-rail swing referenced to VDD, compatible with FPGA/ASIC clock inputs.
8	VDD	Positive supply pin - accepts either 2.5V or 3.3V; decoupling capacitor required within 1cm of pin.

Key Features

Feature	Design Value
Differential Input Flexibility	Single device accepts five industry-standard differential signaling types without external components - reduces BOM count and layout complexity.
Low-Noise Clock Translation	0.11ps RMS additive phase jitter preserves timing integrity for high-speed ADCs, DACs, and JESD204B links.
Supply-Voltage Agnostic Operation	Validated performance at both 2.5V and 3.3V eliminates need for separate voltage rails in mixed-voltage systems.
Controlled Output Enable	OE pin allows dynamic clock gating with 8ns enable/disable timing - supports low-power states in battery-operated or thermally constrained systems.
Space-Efficient Packaging	Standard 8-lead SOIC footprint fits dense PCB layouts while maintaining manufacturability and thermal performance (θJA = 93.1°C/W).

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential-to-single-ended clock translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NB3N551DR2G	Supports only LVDS and LVPECL inputs; lacks LVHSTL/SSTL/HCSL compatibility; 250MHz max frequency.	Suitable for legacy LVDS-only systems but not drop-in for multi-standard designs requiring HCSL or SSTL.	Select when cost sensitivity outweighs input flexibility and frequency headroom.
Microchip SY100EL15ZC	ECL-compatible only; requires negative supply (–5.2V); no LVCMOS/LVTTL output - needs external level shifter.	Applicable only in ECL-based timing subsystems; incompatible with modern 2.5V/3.3V digital logic domains.	Choose only for retrofitting older ECL timing architectures where supply infrastructure exists.

Compared with NB3N551DR2G and SY100EL15ZC, the 830S21AMI-01LF provides broader input standard coverage, higher frequency margin (350MHz vs. 250MHz), and native LVCMOS/LVTTL output compatibility - reducing component count and improving timing fidelity in mixed-signal telecom and test equipment designs.

FAQ

What input signal standards does the 830S21AMI-01LF support?

The 830S21AMI-01LF supports LVPECL, LVDS, LVHSTL, SSTL, and HCSL differential input standards. Its CLK/nCLK inputs accept these signal types without external biasing or termination components due to integrated 51kΩ pullup/pulldown resistors and wide common-mode range (GND+0.5V to VDD–0.85V). This multi-standard compatibility is confirmed in the official Renesas datasheet Section 8.

Does the 830S21AMI-01LF require external termination resistors?

No, the 830S21AMI-01LF does not require external termination resistors for standard LVDS, LVPECL, or HCSL inputs. Its differential inputs include internal 51kΩ pullup and pulldown resistors, and the datasheet confirms proper operation with common driver topologies including IDT LVHSTL, 3.3V LVPECL, and 2.5V SSTL sources. External termination is only needed if driver vendor specifications mandate it.

What is the maximum output frequency specification for the 830S21AMI-01LF?

The maximum output frequency for the 830S21AMI-01LF is 350MHz, as specified in Tables 5A and 5B of the Renesas datasheet under AC Electrical Characteristics. This rating applies across both 2.5V and 3.3V supply conditions and ambient temperatures from –40°C to +85°C, making it suitable for high-speed SerDes reference clocks and DDR4 memory timing applications.

How does the OE pin function on the 830S21AMI-01LF?

The OE (Output Enable) pin on the 830S21AMI-01LF is an active-high control input. When OE = 0, the Q output enters a high-impedance state; when OE = 1, the Q output is enabled and follows the translated clock signal. The datasheet specifies 8ns enable/disable timing and confirms internal pullup, ensuring default-enabled operation at power-up unless actively driven low.

Is the 830S21AMI-01LF pin-compatible with other devices in the same family?

Yes, the 830S21AMI-01LF shares identical pinout and package (8-lead SOIC, M suffix) with other members of the 830S21x family, including the 830S21I-01 and 830S21AMI-01. Pin assignments for CLK, nCLK, OE, Q, VDD, GND, and nc positions are consistent across these variants, enabling direct substitution where temperature grade and packaging (tube vs. tape-and-reel) align with design requirements.
