TK14588 - FM IF IC

Toko Inc 2009/05/29 09:24
DESCRIPTION
The TK14588V is a standard function general purpose IF IC capable of operating up to 22 MHz. The TK14588V contains a high-speed data comparator for base band processing. The TK14588V has a unique function that allows establishing the demodulation characteristics by changing the external RC time constant, and not changing the phase shifter constant. The RSSI output is individually trimmed, resulting in excellent accuracy, good linearity, and stable temperature characteristics. The TK14588V was developed for high-speed data communication, DECT, wireless LAN, keyless entry systems, etc.
The TK14588V is available in the very small TSSOP-16 surface mount package.

FEATURES
*Input Frequency (~22 MHz)
*Low Voltage Operation (2.3 to 5.5 V)
*Battery Save Function
*Wide Band Demodulator (~1 MHz)
*High Speed Data Comparator (~2 Mbps)
*Very Small Package (TSSOP-16)

APPLICATIONS
*Communications Equipment
*Wireless LAN
*Keyless Entry Systems

GENERAL DESCRIPTION
The TEA5768HL is a single-chip electronically tuned FM stereo radio for low-voltage applications with fully integrated IF selectivity and demodulation. The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US and Japanese FM bands.

FEATURES
· High sensitivity due to integrated low-noise RF input amplifier
· FM mixer for conversion to IF of the US/Europe
  (87.5 MHz to 108 MHz) and Japanese
  (76 MHz to 91 MHz) FM band
· Preset tuning to receive Japanese TV audio up to 108 MHz
· RF Automatic Gain Control (AGC) circuit
· LC tuner oscillator operating with low cost fixed chip inductors
· FM IF selectivity performed internally
· No external discriminator needed due to fully integrated FM demodulator
· Crystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clock crystal or with a 13 MHz crystal and with an externally applied 6.5 MHz reference frequency
· PLL synthesizer tuning system
· I2C-bus
· 7-bit IF counter output via the I2C-bus
· 4-bit level information output via the I2C-bus
· Soft mute
· Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)]
· Signal dependent High Cut Control (HCC)
· Soft mute, SNC and HCC can be switched off via the I2C-bus
· Adjustment-free stereo decoder
· Autonomous search tuning function
· Standby mode
· Two software programmable ports
· Bus enable line to switch the bus input and output lines into 3-state mode
