Description
The AK8130AH is a member of AKM’s low power
multi clock generator family designed for a feature
rich DTV or STB, requiring a range of system
clocks with high performance. The AK8130AH
generates different frequency clocks from a 27MHz
crystal oscillator and provides them to up to four
outputs configured by pin-setting. The on-chip
VCXO accepts a voltage control input to allow the
output clocks to vary by ±110 ppm for
synchronizing to the external clock system. Both
circuitries of VCXO and PLL in AK8130AH are
derived from AKM’s long-term-experienced clock
device technology, and enable clock output to
perform low jitter and to operate with very low
current consumption. The AK8130AH is available
in a 16-pin TSSOP package.

(1) Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only. Functional operation of the device at these or any other conditions beyond those
indicated under “Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rating
conditions for extended periods may affect device reliability. Electrical parameters are guaranteed only over the

Output clock frequency selection
The AK8130AH generates a range of low-jitter and hi-accuracy clock frequencies with three built-in PLLs
and provides to up to four assigned outputs. A frequency selection at assigned output pin is configured by
pin-setting of S0 (Pin2), S1 (Pin3), and S2 (Pin14).
The selectable frequency is shown in Table 1..

Voltage Control Crystal Oscillator (VCXO)
The AK8130AH has a voltage control crystal oscillator (VCXO), featuring fine frequency tuning for 27MHz
of primary clock frequency by external DC voltage control. This tuning enables output clock frequency to
synchronize the external clock system. VIN (Pin 4) accepts DC voltage control from a processor or a
system controller, and pulls the primary frequency of crystal to higher or lower. This pulling range is
determined by crystal characteristic, on-chip load capacitor, and stray capacitance of PCB. The
AK8130AH is designed to range ±110ppm of primary frequency in AKM’s authorized condition, and the
typical pulling profile is shown in Figure 1. For details about the condition and other specific crystal
application case, refer the AK8130 Family application note.

PCB Layout Consideration
The AK8130AH is a high-accuracy and low-jitter multi clock generator. For proper performances specified
in this datasheet, careful PCB layout should be taken. The followings are layout guidelines based on the
typical connection diagram shown in Figure 2
Power supply line – AK8130AH has three power supply pins (VDD1-3) which deliver power to internal
circuitry segments. A 0.1F decoupling capacitor should be placed as close to each VDD pin as possible.
Ground pin connection – AK8130AH has two ground pins (GND1-2). These pin require connecting to
plane ground which will eliminate any common impedance with other critical switching signal return.
0.1F decoupling capacitors placed at VDD1, VDD2, and VDD3 should be grounded at close to the
GND1pin, the GND2 pin, and the GND2, respectively.
Crystal connection – Proper oscillation performance and pullable range are susceptible to stray or
parasitic capacitors around crystal. The wiring traces to a crystal form X1 (Pin 1) and X2 (Pin 14) have
equal lengths with no via and as short in length as possible. These traces should be also located away
from any traces with switching signal.
