EME9M296206000/1/1AA DUAL PDLULAFLOPRLL4F6O/4R9 4M6/4H9ZMCHOZ RCODRLDELSESSSPPHHOONNEE GENERAL DESCRIPTION The EM92600/1A series are developed for 46/49 MHz of 10 channels band frequency of cordless telephone which is used in U.S.A.. These devices are dual phase-locked loop frequency synthesizers contained ROM counters for receive and transmit loops with two independent phase detect circuits. A common reference oscillator and reference divider are share by the receive and transmit circuits. Other features include a lock detect circuit for the transmit loop, illegal code default, a buffered oscillator output for mixing purposes in the system, 5KHz tone output . The EM92601A is designed for easy MPU interface. It provides the same features as the EM92600A , but accepts channel programming via a clocked, serial input instead of parallel BCD inputs. The EM92600A is selected channels via machanical switches of parallel BCD input. FEATURES • Include oscillation circuit with external X-TAL (10.240 MHz). • Unlock detector. • 5KHz output for guard tone. • Standby mode for power saving. • 2.5 to 5.5V supply range. • Baseset/Handset changeable. • Available in 16 pin DIP or SOP. • SERIES Part Number Package Channel Selection EM92600AP DIP parallel EM92600AM SOP parallel EM92601AP DIP serial EM92601AM SOP serial PIN ASSIGNMENTS EM92600A XTALO MODE SB 5K D0 D1 D2 D3 1 2 3 4 5 6 7 8 16 XTALI 15 VDD 14 RIF 13 PDR 12 VSS 11 PDT 10 LD 9 TIF EM92601A XTALO MODE SB 5K DI CLK NC EN 1 2 3 4 5 6 7 8 16 XTALI 15 VDD 14 RIF 13 PDR 12 VSS 11 PDT 10 LD 9 TIF * This specification are subject to be changed without notice. 4.23.1995 1 1 page EM92600/1A DUAL PLL FOR 46/49 MHZ CORDLESS PHONE TIMING DIAGRAM Data Clock Enable D3 tw 1 st CLK PDT LD APPLICATION CIRCUIT D2 tsu th 2 nd CLK D1 3 rd CLK EM92601A Timing 1.6µS D0 4 th CLK tw tsu 1 st CLK trec Previous Data Latched 6.4±0.4mS Unlock Timing 0.455MHz 2ND IF 2ND MIX 1ST IF 1ST MIX BPF RX VCO LPF LPF TX VCO BPF 16 15 14 13 12 11 10 9 10.240 MHz 12 34 56 78 * This specification are subject to be changed without notice. 4.23.1995 5 5 Page
