AK8133E

Overview

The AK8133E is a low-suppression multiclock generator designed for high-quality audio applications. It generates multiple clock frequencies from a 27MHz crystal oscillator or external input, providing four selectable outputs and one reference output. The device features built-in XO and PLL circuitries to ensure low jitter performance with a typical period jitter of 30 ps. Operating on a single supply voltage between 2.85V and 3.6V, it consumes approximately 18.0mA at 3.3V. The component is housed in a lead-free 16-pin SSOP package and supports an operating temperature range of -20°C to +85°C.

Feature Summary

• Generates up to four frequency-selectable clock outputs plus one 27MHz reference output using internal PLLs and a built-in crystal oscillator.
• Delivers low jitter performance with a typical period jitter of 30 ps across all clock outputs.
• Configurable via pin-setting (S0-S3) to support standard sampling frequencies including 44.1kHz, 48kHz, 96kHz, and 192kHz.
• Low current consumption of 18.0mA (typical) at 3.3V supply voltage.

Applications

• Personal Video Recorders
• Set-Top-Boxes
• Multi Media Receivers

Procurement Notes

Verify the ordering suffix 'E' confirms the -20°C to +85°C operating temperature range, distinct from the 'V' suffix which covers -40°C to +85°C. Confirm the shipping packaging is tape and reel as specified for this part number. Ensure the source document identifies Asahi Kasei EMD Corporation (AKEMD) as the manufacturer.

Selection Notes

Select the AK8133E when the application requires a 16-pin SSOP package and operates within the -20°C to +85°C temperature range. Choose this model over the AK8133V if extended cold-temperature operation below -20°C is not required. Ensure the design accommodates the 2.85V to 3.6V supply voltage and utilizes pin-setting logic for frequency configuration.

Part Context

The AK8133E belongs to AKEMD’s low power multi-clock generator family, engineered for high-performance audio systems requiring precise timing. It shares the same core architecture and package as the AK8133V, differing primarily in the guaranteed operating temperature range. The device integrates both XO and PLL technologies to minimize jitter while maintaining low power consumption.

Replacement Considerations

The AK8133V is a direct functional substitute with identical electrical characteristics and pinout, differing only in the guaranteed operating temperature range (-40°C to +85°C vs. -20°C to +85°C). Verify that the ambient temperature conditions of the target application fall within the -20°C lower limit of the AK8133E before substituting.

FAQ

How are the clock output frequencies configured?

Frequencies are selected by setting the logic levels of pins S0, S1, S2, and S3. Internal pull-up resistors are present on S0, S1, and S3, while S2 requires connection to VDD for a high state.

What is the difference between the AK8133E and AK8133V?

The primary difference is the operating temperature range. The AK8133E is rated for -20°C to +85°C, whereas the AK8133V is rated for -40°C to +85°C.

Can the AK8133E accept an external clock input?

Yes, the device accepts a 27MHz external clock input at the XIN pin with a minimum amplitude of 1Vpp. In this mode, the XOUT pin should be left open.
