Product details

Overview

87001BGI-01LFT from Integrated Device Technology (IDT) is a low-skew, programmable LVCMOS/LVTTL clock divider IC with ÷1 to ÷16 integer division ratios, 250 MHz maximum output frequency, and dual selectable single-ended clock inputs. It features separate core (VDD) and output (VDDO) supply rails supporting mixed-voltage operation (e.g., 3.3V/1.8V), output enable control, and guaranteed part-to-part skew of ≤750 ps (typ. 135 ps). It serves as a timing synchronization element in FPGA clock trees, industrial controllers, and communications baseband subsystems.

For engineers reviewing the 87001BGI-01LFT datasheet, 87001BGI-01LFT pinout, 87001BGI-01LFT application, or 87001BGI-01LFT equivalent, this page delivers verified electrical parameters, validated TSSOP-16 pin mapping, real-world use scenarios, and two confirmed alternative clock dividers for design flexibility and supply continuity.

Technical Context

The 87001BGI-01LFT implements a synchronous digital divider architecture with three binary-selectable N[2:0] inputs controlling division ratio (÷1–÷16), CLK_SEL choosing between CLK0 or CLK1, and OE enabling/disabling the Q output into high-impedance state. All inputs accept LVCMOS/LVTTL logic levels with internal 51 kΩ pullup/pulldown resistors.

It supports five independent power supply configurations (e.g., VDD/VDDO = 3.3V/1.8V, 2.5V/2.5V), enabling interface bridging across voltage domains. Propagation delay varies by division ratio (3.5–7.7 ns typical), and output rise/fall times remain ≤2.5 ns under worst-case 1.8V operation - critical for maintaining signal integrity in multi-rail timing systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Output Frequency	250 MHz - enables direct clocking of high-speed FPGA I/O banks or ADC sampling clocks without external PLL multiplication.

Pinout & Package

87001BGI-01LFT is housed in a lead-free, RoHS-compliant 16-lead TSSOP (G package) measuring 4.4 mm × 5.0 mm × 0.925 mm, optimized for high-density PCB layouts and thermal performance on multi-layer boards (θJA = 100.3°C/W at 0 m/s airflow).

Pin/Terminal	Circuit Role	Design Meaning
1 (OE)	Output enable input	LVCMOS/LVTTL active-high control: drives Q into high-Z when LOW; enables clock output when HIGH - essential for clock gating in power-managed systems.
2 (VDD)	Core supply	Supplies internal logic and input buffers; supports 2.5V or 3.3V ±5% - decoupling required per datasheet layout guidelines.
3,5 (CLK0, CLK1)	Single-ended clock inputs	Accept LVCMOS/LVTTL signals; internally pulldown-biased - allows unused input to float safely without external termination.
4 (CLK_SEL)	Clock source selector	LVCMOS/LVTTL input: HIGH selects CLK1, LOW selects CLK0 - enables dynamic clock source switching in redundant timing architectures.
6–8 (N2,N1,N0)	Divider ratio select	3-bit binary input defining division factor per Table 3; internally pulldown-biased - no external pull resistors needed for default ÷1 operation.
9,12 (GND)	Ground reference	Dual ground pins reduce noise coupling and improve PSRR; must be connected to low-impedance PCB ground plane.
10,11,13,15 (nc)	No-connect terminals	Unused silicon pads; left unconnected per design - no routing or soldering required.
14 (Q)	Clock output	LVCMOS/LVTTL single-ended output; impedance-matched to 17–28 Ω depending on VDDO - requires 50 Ω termination to VDDO/2 for AC-coupled measurement compliance.
16 (VDDO)	Output supply	Independent rail setting output voltage level (1.8V/2.5V/3.3V); isolates output swing from core logic - enables mixed-signal domain interfacing.

Key Features

Feature	Design Value
Programmable division ratio	Hardware-selectable ÷1–÷16 via N2:N0 pins - eliminates need for configuration firmware or external logic, reducing BOM count and boot-time latency.
Dual clock input with selector	CLK0/CLK1 + CLK_SEL pin - supports failover clocking or multi-source timing (e.g., primary crystal + backup oscillator) without external multiplexers.
Independent VDD/VDDO supplies	Separate core and output rails - enables clean 1.8V clock generation from a 3.3V system supply, avoiding level-shifters and associated jitter penalties.
Low part-to-part skew	≤750 ps max over temperature and voltage - guarantees consistent timing margins across multiple synchronized boards or modules in rack-mounted systems.
Integrated input biasing	51 kΩ internal pullup/pulldown resistors on all control and clock inputs - removes requirement for external biasing components, simplifying layout and improving reliability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ICS87002BGI-01LFT	Dual-output version (Q0/Q1) with identical division ratios, skew, and supply flexibility; same TSSOP-16 package.	Required when two independent, synchronized divided clocks are needed (e.g., TX/RX clock pairs), not single-output use cases.	Select 87001BGI-01LFT for cost-optimized single-clock applications; choose ICS87002BGI-01LFT only if dual outputs provide net BOM or layout savings.
PI6C20400LEX	Quad-output LVCMOS divider (÷1–÷32), higher max frequency (350 MHz), but fixed 3.3V-only supply; larger 24-pin TSSOP package.	Suitable for systems needing >1 output or wider division range, but incompatible with 1.8V/2.5V mixed-supply designs.	Choose PI6C20400LEX only when quad outputs or >250 MHz operation are mandatory; 87001BGI-01LFT remains optimal for mixed-voltage, single-output precision timing.

Compared with ICS87002BGI-01LFT and PI6C20400LEX, the 87001BGI-01LFT offers the lowest cost and smallest footprint for single-output, mixed-supply clock division - making it ideal for space-constrained industrial and communications edge devices where voltage flexibility and skew control outweigh channel count or extreme frequency needs.

FAQ

What is the maximum input clock frequency supported by the 87001BGI-01LFT?

The 87001BGI-01LFT accepts input clock frequencies up to 250 MHz across all supported supply configurations (e.g., VDD/VDDO = 3.3V/3.3V, 3.3V/1.8V). This limit applies regardless of division ratio - for example, a 250 MHz input yields 250 MHz output at ÷1, or 15.625 MHz at ÷16. The device maintains specified AC performance (propagation delay, skew, duty cycle) within this range.

Does the 87001BGI-01LFT require external pull-up or pull-down resistors on its control pins?

No. The 87001BGI-01LFT integrates internal 51 kΩ pullup resistors on OE and internal 51 kΩ pulldown resistors on CLK_SEL, CLK0, CLK1, and N2–N0 pins. These eliminate the need for external biasing components, simplifying PCB layout and improving reliability. Unused clock inputs may be left floating per datasheet guidance.

Can the 87001BGI-01LFT generate a 1.8V LVCMOS clock output while powered by a 3.3V core supply?

Yes. The 87001BGI-01LFT supports independent VDD (core) and VDDO (output) supplies. With VDD = 3.3V ±5% and VDDO = 1.8V ±0.15V, it delivers a fully compliant 1.8V LVCMOS output (VOH ≥1.25V, VOL ≤0.4V) while operating internal logic at 3.3V - enabling direct interface to 1.8V FPGAs or ASICs without external level shifters.

What is the guaranteed part-to-part skew specification for the 87001BGI-01LFT?

The 87001BGI-01LFT guarantees part-to-part skew of ≤750 ps under all operating conditions (−40°C to +85°C, full supply range), with a typical value of 135 ps. This parameter is defined per JEDEC Standard 65 and measured across devices with identical supply voltages, input frequencies, temperatures, and load conditions - critical for multi-board synchronization.

Is the 87001BGI-01LFT pin-compatible with other members of the ICS87001 family?

Yes. The 87001BGI-01LFT shares identical pinout, package (16-lead TSSOP), and functional interface with all variants in the ICS87001 family, including ICS87001I-01 and ICS87002BGI-01LFT. This allows drop-in replacement for single-output configurations and straightforward migration to dual-output versions where needed.
