概述

Description

CDCM1804RGER is a 4-output clock distribution buffer from the CDCM1800 family. It takes a single reference clock input and fans it out to four synchronized outputs with low jitter and low skew, suitable for distributing clocks to FPGAs, CPUs, SerDes, memories, and other digital logic. Key features typically include low additive jitter, fast startup, and selectable output characteristics with enable/power-down options. The “RGER” suffix indicates RoHS-compliant, tape-and-reel packaging. For exact electrical specs (frequency range, output formats, drive strength, skew, jitter, and pinout), refer to the official CDCM1804RGER datasheet.

Features

Key features of CDCM1804RGER (concise):
- 1 reference input with 4 clock outputs (fanout buffer)
- Flexible output formats: selectable LVPECL, LVDS, CML, or HCSL per output
- Low-jitter clock distribution with onboard jitter-cleaning capability
- Optional spread-spectrum clocking (SSC) to reduce EMI
- Independent output enables and a global/power-down mode
- Low skew between outputs for synchronized multi-clock systems
- Single-supply operation (RoHS-compliant, typical industrial temp range)
- Small package footprint suitable for space-constrained designs
Note: exact frequency range, jitter specs, supply voltages, and package details are in the datasheet.

Package

CDCM1804RGER is in a 16-pin surface-mount package, specifically a TSSOP-16 package.

Manufacturer

- Manufacturer: Integrated Device Technology (IDT).
- What kind of company: A semiconductor company that designs and manufactures integrated circuits, including timing/clock distribution devices (now part of Renesas Electronics).

Application

CDCM1804RGER is a multi-output clock distribution device. Typical applications include:
- Clock distribution for FPGAs/ASICs and CPUs
- Memory interface timing (DDR/LPDDR)
- SERDES and high-speed data links (PCIe, Ethernet, SATA, USB3)
- Telecom/datacom equipment and networking gear
- Backplanes, data centers, instrumentation and test equipment

Equivalent

Equivalent parts (clock distribution/jitter-cleaning with ~4 outputs) from other vendors include:
- Analog Devices: AD9523, AD9524 (4-output jitter-cleaning clock distribution)
- Silicon Labs: Si5338 (and Si532x family)
- Texas Instruments: CDCLVC1104 / CDCE6xx family (clock buffers/distributors)
Note: exact pinout, input/output types, and jitter specs differ; use cross-reference tools to match frequency, outputs, and packaging.
