STCD1020RDG6F

Clock Buffers, Drivers Overview

The STCD1020RDG6F is a multichannel clock distribution circuit featuring two buffered outputs. It operates on a single supply voltage ranging from 2.5 V to 3.6 V, with a typical rating of 2.8 V. The device accepts single-ended sine wave or square wave clock inputs between 10 MHz and 52 MHz. Key electrical parameters include an additive phase noise of -135 dBc/Hz at 1 kHz offset and a standby current of 1 µA when all buffers are disabled. It utilizes a TDFN8 package (2 mm x 2 mm) and supports an operating temperature range of –40 °C to +85 °C.

Clock Buffers, Drivers Feature Summary

• Provides 2 buffered unity gain clock outputs with individual enable control for each channel.
• Accepts single-ended sine wave or square wave clock inputs without requiring AC coupling capacitors at the input.
• Features ultra-low phase noise (-135 dBc/Hz at 1 kHz offset) and low standby current (1 µA).
• Capable of driving a typical load of 10 pF per output.

Clock Buffers, Drivers Applications

• Multimode RF clock reference in mobile phones.
• Baseband peripheral devices clock reference such as WLAN, Bluetooth, GPS, and DVB-H.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix RDG6F against official documentation to confirm package type and environmental compliance. Check product status as some variants in this series may be listed as End-of-Life or Lifebuy. Ensure the design accommodates the TDFN8 thermal characteristics and soldering requirements specified in the datasheet.

Clock Buffers, Drivers Selection Notes

Select the STCD1020 variant specifically for applications requiring exactly two clock outputs. If three or four channels are needed, consider the STCD1030 or STCD1040 respectively. Ensure the master clock source voltage level does not exceed the supply rails if connected directly; otherwise, external DC-cut capacitors and biasing resistors are required.

Clock Buffers, Drivers Part Context

The STCD1020 belongs to the 1040 Series of PLL-based clock drivers manufactured by STMicroelectronics. This series includes the STCD1030 (3 outputs) and STCD1040 (4 outputs), sharing similar electrical characteristics and pinout structures while differing in channel count and package lead numbers (TDFN10 and TDFN12).

Clock Buffers, Drivers Replacement Considerations

Direct pin-to-pin substitutes within the same family include the STCD1030RDH6E and STCD1040RDM6F, provided additional unused outputs can be managed via enable pins. Verify that the replacement part number matches the required channel count and package dimensions.
