A S A H I K A SE I E M D C O R P O R A TIO N Register Programmable Clock Generator AK8141 Features · · Description The AK8141 is a single clock generator IC with an integrated PLL. It can generate a 27.0MHz – 50.0MHz by 1MHz step or 33.75MHz, 40.5MHz, 49.5MHz clock from a 48MHz, 24MHz, 12MHz and 27MHz master clock input frequency. The output can be enabled or disabled with pin and the frequency can be changed via three-line serial interface. The high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal. · · · · · · Input Frequency: 48MHz/24MHz/12MHz/27MHz (Selectable) Output Frequency: 27MHz – 50MHz by 1MHz step, 33.75MHz/40.5MHz/49.5MHz (Selectable) Low Jitter Performance: 15 ps (Typ.) Period 1s Low Current Consumption: 3.5mA (Typ.) at 27MHz, 3.0V 4.5mA (Typ.) at 50MHz, 3.0V Output Load: 15pF(Max) Supply Voltage: 2.7 – 3.6V Operating Temperature Range: -20 to +85℃ Package: 8-pin USON Applications · · Digital Still Camera Digital Video Camera Block Diagram VDD VSS CLKIN INPUT Buffer PLL OUTPUT Buffer CLKOUT OE Register XLAT SCLK SDATA AK8141 Register Programmable Clock Generator MS0607-E-00 1 May-08 http://www.Datasheet4U.com AK8141 The brand name of AKEMD’s IC’s PIN DESCRIPTION Package: 8-Pin USON ( Top View) Pin No. 1 2 3 Pin Name OE VDD VSS Pin Type IN --- Description CLKOUT output enable control “L”: CLKOUT=”L” and power down. “H”: active Power supply Ground Clock output Output clock frequency is selectable to 27.0MHz or 50.0MHz by 1MHz step, or 33.75MHz, 40.5MHz, 49.5MHz through the three-line serial interface. In power down mode (OE = “L”), this pin is “L”. Serial data input Serial clock input Serial write control 8-bits serial data is stored at the rising edge of this input. Set “H” except during serial write process Clock input Input frequency is selected from 48MHz, 24MHz, 12MHz or 27MHz via the serial interface. Place the AK8141 in power down (OE = “L”) mode when an input clock is not supplied. Unstable input to the CLKIN causes the unstable CLKOUT signal. DC input to the CLKIN also causes the unstable CLKOUT signal.
