Philips Semiconductors
Radio tuning PLL frequency synthesizers
Product specification
TSA6057; TSA6057T
FEATURES
• On-chip AM and FM prescalers with high input
sensitivity
• On-chip high performance one input (two output) tuning
voltage amplifier for the AM and FM loop filters
• On-chip 2-level current amplifier (charge pump) to
adjust the loop gain
• Only one reference oscillator (4 MHz) for both
AM and FM
• High speed tuning due to a powerful digital memory
phase detector
• 40 kHz output reference frequency for co-operation with
the FM/IF system and microcomputer-based tuning
interface IC (TEA6100)
• Oscillator frequency ranges of: 512 kHz to 30 MHz and
30 to 150 MHz
• 3 selectable reference frequencies of 1, 10 or 25 kHz
for both tuning ranges
• Serial 2-wire I2C-bus interface to a microcontroller and
one programmable address input
• Software controlled band switch output.
GENERAL DESCRIPTION
The TSA6057 is a bipolar single chip frequency
synthesizer manufactured in SUBILO-N technology
(components laterally separated by oxide). It performs all
the tuning functions of a PLL radio tuning system. The IC
is designed for application in all types of radio receivers.
