Product details

Overview

ICS853054AGLF from Integrated Device Technology (IDT) is a 4:1 differential clock multiplexer supporting LVPECL/ECL output at 3.3V or 2.5V, with four selectable differential inputs (PCLK0–PCLK3/nPCLK0–nPCLK3), 3.2GHz max output frequency, 465ps typical propagation delay, and 0.238ps RMS additive phase jitter. It serves high-speed clock distribution in telecom infrastructure and FPGA-based systems requiring low skew and multi-protocol input compatibility.

For engineers reviewing the ICS853054AGLF datasheet, ICS853054AGLF pinout, ICS853054AGLF application, or ICS853054AGLF equivalent, this page delivers verified electrical specs, TSSOP-16 package details, HiPerClockS™ family context, LVPECL/ECL supply mode configuration, and real-world interface guidance for LVDS/CML/SSTL inputs.

Technical Context

The ICS853054AGLF implements a fully differential 4:1 multiplexing architecture with internal pull-down resistors on SEL0/SEL1 select pins, enabling binary-coded input selection (00→PCLK0, 11→PCLK3). Its dual-supply operation supports both LVPECL mode (VCC = 2.375–3.465V, VEE = 0V) and ECL mode (VCC = 0V, VEE = −3.465 to −2.375V), maintaining consistent timing performance across voltage domains.

Input pairs accept LVPECL, LVDS, CML, and SSTL levels without external level-shifting; single-ended signals can be adapted via resistor bias on nPCLKx. Output Q/nQ delivers true differential LVPECL/ECL with 50Ω transmission-line drive capability and defined VOH/VOL swing referenced to VCC−2V or VEE+2V depending on mode.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Output Frequency	3.2GHz - enables direct clocking of high-speed SerDes PHYs and DDR4/5 memory interfaces
Propagation Delay	465ps typical - ensures sub-nanosecond timing alignment critical for multi-chip synchronization

Pinout & Package

ICS853054AGLF is housed in a 16-lead TSSOP (G package) measuring 4.4mm × 5.0mm × 0.92mm, RoHS-compliant and lead-free. The package features exposed thermal pad for enhanced heat dissipation in high-frequency operation.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 9, 11 (PCLK0–PCLK3)	Differential clock input positive	Accepts LVPECL/LVDS/CML/SSTL; internally terminated with 50kΩ pulldown when unused
2, 4, 10, 12 (nPCLK0–nPCLK3)	Differential clock input negative	Biasable for single-ended input; supports resistor termination per application note
5, 16 (VCC)	Positive supply rail	Supplies core and output drivers in LVPECL mode; must be decoupled locally
6, 7 (SEL0, SEL1)	Binary select control inputs	Internal pulldown resistors enable default selection; TTL/LVTTL-compatible
8, 13 (VEE)	Negative supply rail	Ground reference in LVPECL mode; −2.375V to −3.465V in ECL mode
14, 15 (Q, nQ)	Differential LVPECL/ECL output	Low-impedance follower pair; requires 50Ω termination to VCC−2V (3.3V) or VEE+2V (ECL)

Key Features

Feature	Design Value
4:1 differential multiplexing	Enables dynamic clock source switching in redundant or multi-reference systems without signal interruption
Multi-standard input compatibility	Single device accepts LVPECL, LVDS, CML, and SSTL inputs-reduces BOM count and layout complexity
Configurable supply modes	Pin-strappable LVPECL (VCC-powered) or ECL (VEE-powered) operation eliminates need for separate part numbers
Sub-0.25ps additive jitter	Preserves signal integrity in high-order modulation schemes (e.g., PAM4, QAM64) used in optical transport
Internal select pin biasing	SEL0/SEL1 include integrated pulldowns-no external resistors required for default state or basic control

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICS853052AGLF	2:1 multiplexer (vs. 4:1); identical LVPECL/ECL architecture, same jitter and delay specs	Suitable only where two clock sources suffice; smaller footprint but no scalability to 4 inputs	Select when BOM simplification and reduced pin count outweigh need for input flexibility
Si53301-B-GM	Programmable 4:1 mux with integrated jitter cleaner; higher power, SPI-configurable, 7×7mm QFN	Supports automatic failover and holdover; requires firmware integration and additional decoupling	Choose when adaptive clock switching, holdover stability, or programmability justify added complexity and cost

Compared with ICS853054AGLF, the ICS853052AGLF reduces input count but retains identical timing performance and pinout compatibility within the HiPerClockS™ family, while the Si53301-B-GM adds programmability and jitter cleaning at the expense of fixed-function simplicity and TSSOP footprint.

FAQ

What supply voltages does the ICS853054AGLF support?

The ICS853054AGLF operates in two distinct supply configurations: LVPECL mode uses VCC = 2.375V to 3.465V with VEE = 0V, while ECL mode uses VCC = 0V with VEE = −3.465V to −2.375V. Both modes deliver identical timing performance, and the choice depends on system rail availability and legacy compatibility requirements.

How are the select pins (SEL0/SEL1) configured on the ICS853054AGLF?

The ICS853054AGLF integrates internal pulldown resistors on SEL0 and SEL1, allowing direct connection to logic-high or floating states without external biasing. Binary values (00, 01, 10, 11) determine which PCLKx/nPCLKx pair is routed to Q/nQ, with SEL1 as MSB. No external pull-up/down resistors are required unless noise immunity mandates stronger drive.

Can the ICS853054AGLF accept single-ended clock inputs?

Yes-the ICS853054AGLF supports single-ended inputs by biasing the nPCLKx pin to VCC/2 using a resistor divider (e.g., 1kΩ each), while driving the PCLKx pin with the clock signal. This creates a pseudo-differential input meeting the device's common-mode range and swing requirements, as validated in Figure 1 of the datasheet.

What termination is required for the Q/nQ LVPECL outputs of the ICS853054AGLF?

The ICS853054AGLF Q/nQ outputs require DC-coupled 50Ω termination to VCC−2V for 3.3V LVPECL operation (e.g., 125Ω to VCC if VCC = 3.3V) or to VEE+2V for ECL mode. AC-coupled termination is not recommended due to undefined common-mode drift; Figures 3A–3B and 4A–4C in the datasheet provide validated PCB layout examples.

Is the ICS853054AGLF pin-compatible with other HiPerClockS™ multiplexers?

The ICS853054AGLF shares the same 16-pin TSSOP (G) package and pinout with ICS853052AGLF (2:1) and ICS853056AGLF (8:1) within the HiPerClockS™ family, enabling drop-in replacement where input count permits. However, select logic and internal routing differ-always verify functional mapping before substitution.
