RoHS Certificate of Compliance

RS Components
RoHS Certificate of Compliance

EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.

Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.

RS definition of RoHS Compliance:

  • The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
  • and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering

The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:

PBB (Polybrominated Biphenyls)0.1%
PBDE ( Polybrominated Diphenyl Ethers)0.1%
Hexavalent Chromium0.1%
DEHP (Bis (2-Ethylhexl) phthalate)0.1%
BBP (Benzyl butyl phthalate)0.1%
DBP (Dibutyl phthalate)0.1%
DIBP (Diisobutyl phthalate)0.1%

The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".

RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Evaluation Board for AD9523-x Clock Generator

The AD9523-1/PCBZ, from Analog Devices, is an evaluation board for the AD9523-1 device. The AD9523-1 is a low jitter clock generator which provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers. The on-chip VCO tunes from 2.94 GHz to 3.1 GHz.

The AD9523-1 evaluation board is a compact, easy-to-use plat-form for evaluating all features of the AD9523-1. A 122.88 MHz VCXO is mounted on the evaluation board to provide a complete solution.
The input receivers are configured as differential but the evaluation board has baluns to provide a single-ended input for easy evaluation using common laboratory single-ended signal sources. Output 8 is connected to an ADCLK905 clock buffer to provide a way to evaluate the buffer. Although the ADCLK905 is a 1-to-1 buffer, the performance is similar to the larger fanout buffer, for example, the 1-to-2 buffer, ADCLK925. Output 1 and Output 9 are configured with baluns to provide a single-ended output to drive most test equipment. Output 0 is configured for differential zero delay operation.

Features of the AD9523-1/PCBZ:
- Simple power connection using USB connection and on-board LDO voltage regulators
- LDOs are easily bypassed for power measurements
- AC-coupled differential SMA connectors
- SMA connectors for 2 reference inputs, 2 PLL status outputs, 1 reference test input and 2 VCXO interface inputs/outputs
- Microsoft Windows®–based evaluation software with simple graphical user interface
- On-board PLL loop filter
-Easy access to digital I/O and diagnostic signals via I/O header
-Status LEDs for diagnostic signals
-USB computer interface
-Software calculator provides flexibility, allowing programming of almost any rational input/output frequency ratio
