PLL For DTS
TOSHIBA BiCMOS Integrated Circuit Silicon Monolithic
TB2110FN
TB2110FN
The TB2110FN is a highspeed PLL LSI built in a 2 modulus
prescaler that can operate with a 1.5V power supply.
Each function is controlled via three serial bus lines, allowing you
to configure a highperformance digital tuning system.
Features
· Due to a BiCMOS structure, the 1.5V power supply is
stepped up and stabilized by a bipolar circuit to drive the
CMOS section. Therefore, this chip is best suited for digital
tuning system in headphone stereos.
· Built in a prescaler, this IC can operate with TV: 50~250MHz
and FM: 40~150MHz (2 modulus type) for the FMIN input or
at 0.5~40MHz for the AMIN input (2 modulus type or directly
divided).
Weight: 0.31g (typ.)
· Comes with a 20 bit programmable counter, two parallel output phase comparators, crystal oscillator, reference
counter, and a DC / DC converter control circuit.
· The crystal oscillator (X’tal) used in this IC is a 75kHz resonator.
· The reference frequency can be selected from seven frequencies available. (ref = 1.0~25kHz)
· A 20 bit generalpurpose counter is built in that can measure the IF and other frequencies.
· All device operations are controlled via three serial bus lines.
· Operating voltage range: VCC = 1.0~2.5V (Ta = 20~75°C)
· Package is SSOP24pin.
