CALLING LINE ID RECEIVER WITH RING DETECTOR
Product Preview - -
The MC14LC5447 is a silicon gate HCMOS IC designed to demodulate Bell
202 and V.23 1200–baud FSK asynchronous data. The primary application for
this device is in products that will be used to receive and display the calling
number, or message waiting indicator sent to subscribers from participating
central office facilities of the public switched network. The device also contains
a carrier detect circuit and ring detector which may be used to power up the
device.
Applications for this device include adjunct boxes, answering machines,
feature phones, fax machines, and computer interface products.
The MC14LC5447 offers the following performance features. Ring Detector On–Chip Ring Detect Output for MCU Interrupt Power–Down Mode, Less than 1 μA Single Supply: + 3.5 to + 6.0 V Pin Selectable Clock Frequencies: 3.68 MHz, 3.58 MHz, or 455 kHz Two Stage Power–Up for Power Management Control Demodulates Bell 202 and V.23
