All information contained in this datasheet is subject to change without prior notice. HiMARK Technology, Inc. assumes no responsibility for the use of any circuits shown in this datasheet. Description The FS8107E is a serial data input, phase-locked loop IC with programmable input and reference frequency dividers. When combined with a VCO, the FS8107E becomes the core of a very low power frequency synthesizer well-suited for mobile communication applications such as paging systems. Compared to the FS8100, the FS8107E is housed in a smaller package and also implements a separate pin for stand-by control. Features ‹ High maximum input operating frequency — 100 MHz at VDD1 = 1.0 V ‹ Up to 22 MHz internal crystal oscillator reference frequency at VDD1 = 1.0 V ‹ Extremely low current consumption (IDD,total typically 0.4 mA at fFIN = 90 MHz) ‹ 16-bit programmable input frequency divider (including a ÷ 32/33 prescaler) with divide ratio range from 992 to 65535 ‹ 13-bit programmable reference frequency divider (including a ÷ 8 prescaler) with divide ratio range from 40 to 65528 ‹ Optional lock detector output ‹ Charge pump output for passive low-pass filter ‹ Quick-lock signal output for faster locking ‹ Separate pin for stand-by control ‹ TSSOP 16L package (0.65mm pitch) Applications ‹ Pager ‹ Wireless ...
