• Manufacturer Part Number: ml7050la
• Description: Bluetooth Rf Transceiver Ic
• Manufacturer: Oki Semiconductor

PIN CONNECTION DIAGRAM
The ML7050LA provides a low bill-of-material (BOM) Bluetooth solution by minimizing external components. The
design incorporates numerous internal tuning circuits using Gm-C and other leading-edge technologies to reliably
control phase lock loop (PLL), VCO, amplifiers, modulator, and demodulator circuits. The TX-POW, RX_POW,
PLL_POW, PLL-CLK, PLL_DATA, PLL_LE, PLL_OFF, RXD, and TXD connect directly to the complementary
Bluetooth baseband (ML70511LA) device.
