For PIC16F877 and RTC PCF8583 connections see picture below ..
The built-in 32.768 kHz oscillator circuit and the first
8 bytes of the RAM are used for the clock/calendar and
counter functions.
I can't see an external oscillator. There's just a crystal. Some RTC devices have a built-in crystal, e.g. from Epson. For NXP PCF8583In that diagram an external oscillator of 32.768kHz is used with PCF8583.
