GM6535 Datasheet | SK Hynix

features fully programmable receive, transmit, reference, and auxiliary reference counters accessed through an MCU serial interface, this feature allows this device to operate in any CT1 cordless phone application. The device consists of two independent phase detectors for transmit and receive loops. A mon reference oscillator, driving two independent reference frequency counters, provides independent reference frequencies for transmit and receive loops. The auxiliary reference counter allows the user to select an additional reference frequency for receive and transmit loops if required.
