The SY100HA643JI is a part of the SY100H series of clock distribution products from Siliconix/Intersil Corporation. The device is an advanced low-skew high-performance clock buffer/driver which is specifically designed to perform applications requiring either 100MHZ or 200MHZ operation. It is ideally suited for use in system designs where performance, maximal I/O isolation, and low power consumption are critical requirements.

The SY100HA643JI is a low-skew buffer/driver useful for routing clock frequencies up to 200 MHZ. It has a standard hourglass architecture and is designed to reduce or eliminate clock skew between the different outputs in a common clock line. It receives two low-skew clock inputs, one at 100 MHZ and one at 200 MHZ, and provides ten differential clock outputs with the same low-skew. All of the outputs are fully compliant to both TTL and ECL logic levels.

The SY100HA643JI features a patent-pending skew-control circuit that provides exceptionally low clock skew between the different outputs in a common clock distribution line, regardless of loading conditions. The device also features programmable output enable control and clock pulse-width modulation to reduce power consumption in applications where the clocking requirements may be less frequent. Its high speed differential outputs offer significant improvements over single-ended outputs, especially in terms of noise immunity, crosstalk, and EMI/RFI reduction.

The SY100HA643JI offers excellent performance in terms of power consumption and operating temperature. It consumes a maximum of 1.6W of power per package and a maximum of 1.6V of power. The device also features a quiescent current of 12 mA. The power also helps with heat dissipation, as the device can operate over an extended temperature range of -40°C to +85°C.

The SY100HA643JI also features built-in device-level ESD protection. This ESD protection ensures that any intermittent contact between the device and external circuitry does not cause any significant damage to the device, improving the reliability of the application and reducing the risk of damage due to ESD. The device also features integrated EMI/RFI suppression circuitry to ensure improved immunity to unexpected environmental noise.

The SY100HA643JI is a perfect solution for low-skew, high-performance clock distribution designs. It offers superior performance and low power consumption, while providing ESD protection and EMI/RFI emission suppression. The device’s ability to handle different clock frequencies also makes it a great choice for applications where frequency mixing may be required. It would make a great addition to any clock distribution design where reliability and performance are of the utmost concern.
