ABMJB-902-Q78USY-T3

Overview

The ABMJB-902-Q78USY-T3 is a low power MEMS jitter attenuator manufactured by Abracon LLC. It operates on a single 3.3V supply and accepts a 1.536 MHz reference clock input at the REF_IN pin. The device generates an 8.192 MHz output signal on the CLK0 pin with low drive strength (4mA). An additional 2.048 MHz output is available on the CLK2 pin, also with low drive strength. The unit utilizes an OE control pin for output enable functionality and is housed in a compact 2.9 x 2.8 x 1.45 mm SOT23-6L package.

Feature Summary

• Low power MEMS jitter attenuation technology
• Single 3.3V power supply operation
• LVCMOS compatible outputs with configurable drive strengths
• Compact 2.9 x 2.8 x 1.45 mm SOT23-6L surface mount package

Applications

• Clock distribution networks requiring jitter reduction
• Systems needing multiple derived clock frequencies from a single reference
• Portable electronics due to low power consumption and small footprint

Procurement Notes

Verify the specific suffix T3 indicates tape and reel packaging containing 3000 pieces per reel. Confirm that the Q78 configuration matches the required frequency plan of 1.536 MHz input, 8.192 MHz CLK0, and 2.048 MHz CLK2. Ensure ESD handling precautions are observed as the component is moisture sensitive level 1 and ESD sensitive.

Selection Notes

Select this part when a 1.536 MHz reference is available and outputs of 8.192 MHz and 2.048 MHz are required. The Q78 variant specifically provides an Output Enable (OE) pin on position 1. Compare against other Q-series configurations if different frequency ratios or control pins like CSEL or PDB are needed instead of OE.

Part Context

This component belongs to the ABMJB-902 series of low power MEMS jitter attenuators. The series offers various configurations defined by alphanumeric codes such as 104, 151, Q42, and Q78, which determine the input/output frequencies and control pin functions. The -T3 suffix denotes the standard 3000-piece reel packaging option.

Replacement Considerations

Direct replacements must match the 1.536 MHz input and 8.192/2.048 MHz output frequencies. Other ABMJB-902 variants like Q76 or Q74 share the same package but differ in frequency generation and control logic. Verify pinout compatibility, particularly the function of Pin 1 (OE vs others), before substitution.
