S1T8528 Datasheet | Samsung Semiconductor

ENHANCED-1 CHIP CT0 RF IC INTRODUCTION S1T8528 is a 1 CHIP RF IC which can be used in high performance CTO CLP systems at max. 60MHz. S1T8528 is designed to include a receiver, PLL and PANDER to minimize PCB space requirements. Improved RX characteristics such as inter-modulation, spurious response and adjacent channel interface have been included to satisfy the universal standards. The 1 CHIP RF IC has considerably reduced the cost by including a build-in 1’st mixer, low battery detector, f MCU, RSSI, RF regulator and speaker amp. Also, it fulfills carrier detector threshold control, speaker volume control, operating mode selection and MUTE function using S/W, thus making external application easier. 48- QFP- 1010E Features - - - - - - - Operating voltage range: 2.0V ~ 5.5V Typical supply current: 8.9m A at 3.6V Built-in low battery detection function ( selectable 3.45V, 3.3V, 3.0V, 2.2V, 2.1V ) Built-in speaker volume control and speaker amplifier Built-in splatter filter Support mode selection ( Active, Rx, Standby and Inactive mode ) FM Receiver - Excellent Receiver characteristics < 10.7MHz crystal filter used > Input sensitivity 0.7µ Vrms at 12d B SINAD - Adjacent channel rejection > 55d B Spurious rejection (image of the second IF) > 60d B Intermodulation rejection > 50d B - - RSSI ( Linear ) and Carrier detector output ( Digital ) function pander - Easy gain control and application using external ponent - -Included ALC (Automatic Level Control) circuit Universal PLL - RX (TX) divided counter range : 1/16 ~ 1/16383 - Reference frequency divided counter range : 1/16 ~ 1/4095 - Lock detector signal output - Serial interface with MI for controlling each block - Clock Output for MI oscillator substitution.
