Universal Programmable Clock Generator

(UPCG)

Universal Programmable Clock Generator (UPCG)

Features

General Description

■ Integrated phase-locked loop (PLL)

■ Field-Programmable

The CY22801 is a flash-programmable clock generator that

supports various applications in consumer and communications

markets. The device uses the Cypress-proprietary PLL along

with Spread Spectrum and VCXO technology to make it one of

the most versatile clock synthesizers in the market. The device

uses a Cypress-proprietary PLL to drive up to three configurable

outputs in an 8-pin SOIC.

■ Input frequency range:

❐ Crystal: 8 MHz to 30 MHz

❐ CLKIN: 1 MHz to 133 MHz

■ Low-voltage complementary metal oxide semiconductor

(LVCMOS) output frequency:

❐ 1 MHz to 200 MHz (commercial grade)

❐ 1 MHz to 166.6 MHz (industrial grade)

The CY22801 is programmed with an easy-to-use programmer

dongle, the CY36800, in conjunction with the CyClocksRT™

software. This enables fast sample generation of prototype

builds for user-defined frequencies. Cypress’s value-added

distribution partners and third-party programming systems from

BP Microsystems, HiLo Systems, and others, can also be

contacted for large production quantities. A JEDEC file needs to

be configured to program CY22801, which can be generated

using the CyClocksRT™ software.

■ Special Features:

❐ Spread Spectrum

❐ VCXO

❐ Inputs: PD or OE, FS

■ Low-jitter, high-accuracy outputs

■ 3.3 V operation

■ Commercial and industrial temperature ranges

■ 8-pin small-outline integrated circuit (SOIC) package

■ Serial interface for device configuration
