AK8153A

Overview

The AK8153A is a high-performance clock generator IC featuring two outputs: a 12MHz divided clock and a reference clock (REF). It accepts an input frequency of either 60.0MHz or 72.0MHz, selected via the SEL pin. The device operates on a single 1.8V supply with a maximum power consumption of 6.4 mW. It provides low jitter performance, including long-term jitter of 125 ps (p-p) for the REF output. The component is housed in a compact 6-pin USON package measuring 1.4mm x 1.4mm.

Feature Summary

• Dual output configuration providing 12MHz and REF (60/72MHz) clocks without external crystals
• Low current consumption with a maximum power dissipation of 6.4 mW at VDD=1.8V
• Low jitter performance: Period jitter of 25 ps (1σ) for 12M output; Long-term jitter of 125 ps (p-p) for REF output
• Compact 6-pin USON package (1.4mm x 1.4mm) suitable for space-constrained designs

Applications

• Digital Still Camera
• Digital Video Camera

Procurement Notes

Verify the specific ordering suffix and shipping packaging details when sourcing. Confirm that the temperature range matches the application requirements, as the standard AK8153A is rated for -30 to +80℃. Ensure proper ESD handling procedures are followed during installation due to CMOS process sensitivity.

Selection Notes

Select the AK8153A when a low-power, crystal-less clock source is required for video applications. Choose this part if the system requires a 12MHz clock derived from a 60MHz or 72MHz input signal. Verify that the load capacitance requirements (12pF for 12M, 25pF for REF) align with the connected circuitry.

Part Context

The AK8153A belongs to Asahi Kasei Microdevices' family of clock generators designed for multimedia applications. It serves as a solution for generating precise timing signals in digital imaging devices where low jitter and minimal board space are critical constraints.
