Product details

Overview

CY23FP12OXC-003T from Cypress Semiconductor is a field-programmable zero-delay clock buffer with integrated PLL, delivering 12 LVCMOS outputs up to 200 MHz, 35 ps typical output-to-output skew, and dual-bank 2.5 V/3.3 V supply support. It serves as a configurable clock distribution hub in high-performance ASIC and microprocessor reference clock trees.

For engineers reviewing the CY23FP12OXC-003T datasheet, CY23FP12OXC-003T pinout, CY23FP12OXC-003T application, or CY23FP12OXC-003T equivalent, key selection criteria include programmable input/output dividers (M/N/X), S1/S2-selectable configuration modes, bank-specific three-state control, auto power-down on REF failure, and split-supply noise isolation for mixed-voltage timing systems.

Technical Context

The device implements a fully programmable PLL architecture with user-defined M (1–256) and N (1–256) dividers, enabling precise frequency synthesis from 10 MHz to 200 MHz input. Feedback topology supports internal (CLKA0) or external routing, and lock detection is integrated.

Twelve outputs are grouped into two independent banks (A and B), each with dedicated VDD/VSS pins allowing 2.5 V and 3.3 V operation simultaneously. Each bank supports per-pair divider source selection (PLL output or REF), individual output enable/disable, and optional inversion for complementary clock pairs.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Frequency	200 MHz - supports high-speed CPU, FPGA, and ASIC reference clocks without external frequency multiplication.
Output Skew	35 ps typical - ensures tight timing alignment across all 12 outputs within same frequency domain.
Jitter (Cycle-Cycle)	110 ps typical - meets stringent jitter budgets for SerDes PHYs and DDR memory interfaces.
Supply Voltage	3.3 V core (VDDC); 2.5 V or 3.3 V per bank (VDDA/VDDB) - enables mixed-voltage system clocking with rail isolation.
Input Range	10–200 MHz REF input - accommodates crystal oscillators, XO modules, and system-level clock sources.
Shutdown Current	<50 µA - achieved via auto power-down circuit triggered by REF loss or frequency drift.
Package	28-pin SSOP - surface-mount compatible with industrial PCB assembly and thermal management requirements.

Pinout & Package

28-pin SSOP package with thermally enhanced layout; dual-bank power/ground separation (VDDA/VSSA for Bank A, VDDB/VSSB for Bank B) minimizes cross-bank noise coupling and supports independent voltage rail assignment.

Pin/Terminal	Circuit Role	Design Meaning
REF1, REF2	Reference clock inputs	5 V tolerant LVTTL/LVCMOS inputs; REFSEL selects active source for glitch-free failover.
FBK	PLL feedback input	Accepts internal (CLKA0) or external feedback signal; supports both PLL and fanout buffer modes.
CLKA0–CLKA5, CLKB0–CLKB5	Clock outputs (12 total)	LVCMOS outputs grouped in six pairs; each pair supports independent divider source, enable, and inversion.
S1, S2	Configuration select inputs	Two-bit control selecting one of four preprogrammed functional personalities (e.g., PLL vs REF source, drive enable).
VDDA, VDDB, VDDC	Power supply pins	VDDA/VDDB power respective output banks (2.5 V or 3.3 V); VDDC supplies 3.3 V core logic and PLL.
VSSA, VSSB, VSSC	Ground pins	Separate ground returns per bank and core isolate switching noise and improve PSRR.

Key Features

Feature	Design Value
Fully field-programmable flash memory	Reprogrammable up to 100×; enables late-stage design changes and eliminates obsolete inventory risk.
Dual-bank independent supply control	VDDA/VDDB pins allow Bank A and Bank B to operate at different voltages (2.5 V/3.3 V), supporting mixed-signal SoC clocking.
Per-output pair divider source selection	Each of six output pairs selects independently between PLL output or REF input-enabling hybrid clock tree architectures.
Auto power-down on REF failure	Monitors REF rising edges; shuts down PLL and outputs if frequency drops below threshold, reducing system standby current.
S1/S2 selectable configuration modes	Four distinct functional sets (e.g., full PLL, REF bypass, partial enable) stored in flash and selected dynamically in-circuit.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar zero-delay clock buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IDT 8T49N241	Integrated fractional-N synthesizer; higher integration but fixed register map; no field-programmable flash.	Requires pre-defined configuration; lacks S1/S2 runtime mode switching and per-output pair divider source flexibility.	Preferred when deterministic, factory-programmed timing is required and field reprogramming is unnecessary.
ON Semi NB3N502	Non-programmable 2-input, 12-output zero-delay buffer; no PLL; fixed 1:1 or 1:2 fanout only.	Limited to simple clock replication; no frequency translation, phase adjustment, or REF failover capability.	Selected for cost-sensitive, static clock fanout where programmability and jitter performance are secondary.

Compared with IDT 8T49N241 and ON Semi NB3N502, CY23FP12OXC-003T uniquely combines field-programmable flash, S1/S2-selectable configurations, and dual-bank mixed-voltage operation-enabling one hardware design to serve multiple clocking topologies across product variants.

FAQ

Does CY23FP12OXC-003T require external programming before use?

Yes. The device uses flash-based configuration storage and must be programmed using a compatible programmer (e.g., CY3672-USB with CY3692 socket adapter) or third-party systems (BP Microsystems, HiLo) prior to installation. Unprogrammed units default to a basic fanout mode with limited functionality.

Can CY23FP12OXC-003T generate non-integer frequency ratios?

No. The device supports only integer division via M, N, and X dividers (X = 5–130). Fractional-N synthesis is not implemented; output frequencies are constrained to FREF × N / (M × post_divider), where all dividers are integers.

How does the auto power-down feature respond to reference clock interruption?

It monitors REF rising edges continuously. If the interval exceeds a threshold corresponding to ~10 MHz minimum frequency, the device disables the PLL and forces all outputs into three-state, drawing less than 50 µA. This occurs regardless of S1/S2 state or programming configuration.

Is CY23FP12OXC-003T compatible with 1.8 V logic interfaces?

No. All inputs and outputs are LVTTL/LVCMOS compliant with 2.5 V or 3.3 V operation only. Input tolerance extends to 5 V, but output swing and drive strength are specified only for 2.5 V and 3.3 V rails-1.8 V interfacing requires level-shifting.
