Description

AB1120 is a single-chip IC for HID applications, which supports Bluetooth system version
3.0 features including AFH function. It supports sniff sub-rating for longer battery life &
faster re-connect. Bluetooth 3.0 simple-pairing mechanism is also implemented. AB1120’s
scatternet can join up to 3 piconets. It complies with RF transceiver, baseband processor,
PMU, switching regulator, Boost regulator and Li-ion battery charger. Several Serial
Communication Interfaces including USB, UART, I2C and SPI are supported.

Radio Transceiver:

A common RF terminal is shared by the TX/RX paths of AB1120 with embedded TX/RX switch. Only an external balun and 3 matching components are required in the RF port.
A Low-IF architecture is implemented in the receiver part. The receiver sensitivity is –88dBm at basic data rate. The RSSI value which indicates the received signal power level is also measured and provided to the upper layers.

UBA1702 PDF – Line Interrupter Driver and Ringer

Posted on by pinout

Part Number: UBA1702

Function: Line Interrupter Driver and Ringer

Package: DIP 28 Pin Type

Manufacturer: NXP

Images:UBA1702 datasheet

Description

The UBA1702, UBA1702A performs the high voltage interface and ringer functions of the corded analog telephone set in close cooperation with a microcontroller and transmission circuit.

1. Line Interrupter Driver:

A Line Interrupter Driver, often referred to as a “line interrupter,” is a device used to create a break in the electrical circuit of a telephone line. This break is essential for signaling purposes in some telephony applications, particularly in older analog telecommunication systems. When activated, the line interrupter temporarily disconnects the telephone line, allowing for specific signaling patterns to be transmitted.

 

Features

1. Driver for the line interrupter that can be either a PMOST when UBA1702 is used or a PNP when UBA1702A is used

2. Adjustable over-current protection

3. Adjustable over-voltage protection for transmission circuit

4. Adjustable mute (dialling mode voltage; DMO or NSA)

5. Adjustable current loop detection (hook switch status)

Applications:

1. Telephone sets with software controlled ringer function

2. Telephone sets with electronic hook switch.
