Infineon Technologies CY22M1SCALGXC-00

Overview

CY22M1SCALGXC-00 from Cypress Semiconductor is a one-time programmable, PLL-based single-output clock generator optimized for portable electronics. It delivers 1–80 MHz output frequency with ±0.5% typical accuracy, supports 2.5/3.0/3.3 V operation, features programmable capacitor tuning (0.039–5.0 pF), and integrates asynchronous/synchronous PD#/OE control in an 8-pin 1.7 mm × 1.7 mm QFN package - used in digital cameras and handheld navigation devices.

For engineers reviewing the CY22M1SCALGXC-00 datasheet, CY22M1SCALGXC-00 pinout, CY22M1SCALGXC-00 application, or CY22M1SCALGXC-00 equivalent, key selection criteria include its programmable crystal load capacitance, low-power power-down current (25 µA typ), synchronous OE timing guarantee, 1.5 ns max rise/fall time at high drive strength, and factory-programmable PLL configuration for fixed-frequency deployment.

Technical Context

The CY22M1SCALGXC-00 implements a fully configurable PLL with integer-N frequency synthesis, enabling precise output generation from 1 to 80 MHz using either an 8–48 MHz fundamental-mode crystal or 1–80 MHz external reference clock. Its oscillator includes a 8-bit programmable capacitor array (C0–C7) for fine-tuning crystal load capacitance across 0.039–5.0 pF in 0.039 pF steps.

Power management is implemented via a dual-function PD#/OE pin supporting either active-low power-down (disabling PLL and oscillator) or active-high output enable (tristating CLKOUT while sustaining internal clocks). Both modes are configurable for asynchronous or synchronous edge-triggered behavior relative to CLKOUT, with guaranteed full-cycle pulses only on synchronous OE enable.

FAQ

Is CY22M1SCALGXC-00 field-programmable?

No. CY22M1SCALGXC-00 is factory-programmed with fixed PLL configuration, output frequency, capacitor tuning, and power management settings. Field programming requires the CY22M1Sxxx-xxx variant paired with CyClockMaker kit (CY3675-CLKMAKER1) and CyClockWizard software.

What is the maximum allowable load capacitance on CLKOUT?

The device is characterized for C_OUT ≤ 15 pF per AC Electrical Specifications (Page 8). Exceeding this value increases rise/fall times beyond 1.5 ns (high drive) and may degrade jitter performance or cause timing violations in downstream receivers.

Can XIN/CLKIN accept LVCMOS signals?

Yes. XIN/CLKIN accepts CMOS-level inputs: VIH1 = 0.8×VDD (min), VIL1 = 0.2×VDD (max) for PD#/OE; VIH2 = 1.2–2.1 V (CY22M1S) or 1.2–VDD+0.3 V (CY22M1L); VIL2 = –0.2–0.4 V - compatible with standard 1.8/2.5/3.3 V LVCMOS drivers.

Does the device support spread-spectrum clocking?

No. CY22M1SCALGXC-00 does not implement spread-spectrum modulation. Its PLL provides fixed-frequency synthesis only. Spread-spectrum capability is absent from the functional description, register map, and AC specifications in Document 001-49075 Rev. *E.
