Product details

Overview

ICS853P022AMLF from Integrated Device Technology (IDT, acquired by Renesas) is a dual-channel LVCMOS/LVTTL-to-LVPECL clock translator IC used for high-speed clock distribution in telecom and datacom systems. It accepts single-ended LVCMOS or LVTTL inputs and generates two differential 3.3V LVPECL output pairs (Q0/nQ0, Q1/nQ1), supports up to 1.1 GHz output frequency, features 320 ps typical propagation delay, and operates across –40°C to +85°C ambient temperature.

For engineers reviewing the ICS853P022AMLF datasheet, ICS853P022AMLF pinout, ICS853P022AMLF application, or ICS853P022AMLF equivalent, key selection criteria include LVPECL output drive capability, part-to-part skew ≤650 ps, additive phase jitter of 0.03 ps RMS, supply flexibility (LVPECL mode: VCC = 3.0–3.8 V, VEE = 0 V), and compatibility with 50 Ω transmission line termination.

Technical Context

The ICS853P022AMLF implements a dual-channel, single-ended-to-differential translation architecture using internal LVPECL output drivers with active current sources. Each channel accepts rail-to-rail LVCMOS/LVTTL logic levels and delivers complementary LVPECL outputs with defined VOH/VOL swing (e.g., VOH ≈ 2.26 V, VOL ≈ 1.44 V at VCC = 3.3 V).

It supports two operating modes: LVPECL (VCC = 3.0–3.8 V, VEE = 0 V) and ECL (VCC = 0 V, VEE = –3.8 to –3.0 V), with identical AC performance including 1.1 GHz max output frequency and matched rise/fall times (≤130 ps). Propagation delay matching between channels is specified as part-to-part skew ≤650 ps.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Type	Dual differential LVPECL (Q0/nQ0, Q1/nQ1); enables low-noise, high-speed clock fanout into 50 Ω transmission lines.
Max Output Frequency	1.1 GHz; supports OC-192, SONET, and high-speed SerDes reference clocking.
Propagation Delay	320 ps typical; ensures precise timing alignment in multi-clock-domain systems.
Part-to-Part Skew	650 ps maximum; critical for synchronous parallel data paths and multi-device clock synchronization.
Additive Phase Jitter (RMS)	0.03 ps typical; preserves signal integrity in jitter-sensitive PLL and ADC sampling applications.

Pinout & Package

ICS853P022AMLF is housed in an 8-pin TSSOP package (G suffix, 3 mm × 3 mm × 0.95 mm body, JEDEC MO-187 compliant) with exposed pad not electrically connected. Pin assignments are validated per official IDT datasheet Rev. A (Feb 2005).

Pin/Terminal	Circuit Role	Design Meaning
1, 2	Q0, nQ0	Differential LVPECL output pair; requires 50 Ω termination to VCC – 2 V for proper DC bias and signal integrity.
3, 4	Q1, nQ1	Second differential LVPECL output pair; independently driven, matched in delay and skew to Q0/nQ0.
5	VEE	Ground reference for LVPECL mode (0 V); serves as negative supply in ECL mode (–3.0 to –3.8 V).
6	D1	LVTTL/LVCMOS clock input; accepts 0–3.8 V logic levels with VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 3.3 V.
7	D0	Primary LVTTL/LVCMOS clock input; functionally identical to D1, enabling dual independent clock translation.
8	VCC	Positive supply for LVPECL mode (3.0–3.8 V); supplies core logic and output drivers; bypass capacitor required.

Key Features

Feature	Design Value
Dual LVPECL output pairs	Enables simultaneous translation of two independent clock domains without external buffering or fanout ICs.

650 ps max part-to-part skew	Supports tight skew budgets in parallel bus interfaces (e.g., DDR memory clocks, FPGA fabric clocks).
RoHS-compliant lead-free TSSOP	Meets environmental compliance requirements for modern industrial and telecom PCB assembly.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LVCMOS-to-LVPECL translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC100EPT22DTG	Pin-compatible 8-pin SOIC; identical pinout and AC specs but higher power (IEE = 45 mA vs. 35 mA); no RoHS-lead-free option in legacy packaging.	Preferred where board space permits SOIC and legacy inventory exists; less suitable for dense TSSOP layouts.	Select MC100EPT22DTG only if SOIC footprint is already committed and thermal derating margins exceed 102.6°C junction limit.
ON Semiconductor NB7L573MNR2G	Single-channel, 3.3 V LVPECL translator with lower jitter (0.015 ps RMS), but requires external bias resistors and lacks dual-output integration.	Suitable for point-to-point clock routing; not drop-in for dual-clock fanout without doubling component count.	Choose NB7L573MNR2G when absolute minimum jitter dominates design priority and layout allows discrete termination and extra IC area.

Compared with MC100EPT22DTG and NB7L573MNR2G, the ICS853P022AMLF uniquely balances dual-channel integration, 0.03 ps jitter, TSSOP compactness, and RoHS compliance-making it optimal for space-constrained, high-density telecom clock trees where skew matching and thermal efficiency are jointly critical.

FAQ

What is the recommended termination network for ICS853P022AMLF LVPECL outputs?

The ICS853P022AMLF LVPECL outputs require DC-coupled termination to VCC – 2 V using two 50 Ω resistors-one from Qx to VCC – 2 V and one from nQx to VCC – 2 V. This establishes the correct common-mode voltage (~1.3 V) and provides a 50 Ω differential load. The ICS853P022AMLF datasheet specifies RTT = 125 Ω for VCC = 3.3 V, confirming this dual-resistor configuration. Avoid AC coupling unless system-level jitter analysis validates its impact.

Does ICS853P022AMLF support ECL mode operation, and how does it differ from LVPECL mode?

Yes, the ICS853P022AMLF supports ECL mode with VCC = 0 V and VEE = –3.0 V to –3.8 V. In ECL mode, output voltage levels shift negatively (VOH ≈ –1.29 V, VOL ≈ –1.76 V), but AC performance-including 1.1 GHz max frequency, 320 ps propagation delay, and 0.03 ps additive jitter-remains identical to LVPECL mode. The ICS853P022AMLF's dual-supply flexibility allows interoperability with legacy ECL systems without redesigning clock trees.

Can ICS853P022AMLF drive 50 Ω loads directly, and what is the maximum trace length supported?

Yes, the ICS853P022AMLF is designed to drive 50 Ω transmission lines directly. With proper termination and controlled-impedance PCB routing, it reliably supports trace lengths up to 15 cm at 1.1 GHz before significant signal degradation occurs. The ICS853P022AMLF's 130 ps typical rise/fall time and low output skew ensure signal fidelity; however, simulation is recommended for >10 cm traces in multi-layer boards with tight crosstalk constraints.

What is the thermal performance of ICS853P022AMLF in its TSSOP package under full-load conditions?

In its 8-pin TSSOP (G package), the ICS853P022AMLF has θJA = 101.7°C/W at 0 m/s airflow (multi-layer PCB). At worst-case VCC = 3.8 V with both outputs switching, total power dissipation is ~195 mW. At 85°C ambient, calculated junction temperature is 102.6°C-well below the 125°C maximum. The ICS853P022AMLF thus operates safely in industrial environments without forced cooling, provided PCB copper area meets JEDEC standards.

Is ICS853P022AMLF pin-compatible with any industry-standard alternatives, and what validation exists?

Yes, the ICS853P022AMLF is explicitly documented as pin-compatible with ON Semiconductor's MC100EPT22 in the official IDT datasheet (Rev. A, p. 9). Both share identical 8-pin TSSOP/SOIC pinouts, LVCMOS/LVTTL input thresholds, LVPECL output drive strength, and AC timing specs. No PCB changes are required when substituting ICS853P022AMLF for MC100EPT22 in existing designs, though thermal and RoHS compliance should be re-verified.
